This Startup Is Growing Sushi-Grade Salmon From Cells in a Lab

As the ills of factory farming become more pronounced, people are increasingly gravitating towards vegetarian or pescatarian diets. Besides producing a large percentage of our total greenhouse gas emissions, raising livestock uses up a third of the world's arable land to grow feed, not to mention that the animals themselves are often terribly mistreated.

Eating fish, then, seems preferable to meat. In fact, according to the Global Aquaculture Alliance, 3.1 billion people around the world now rely on fish and seafood for a fifth of their animal protein intake. Fish are also one of our only sources of long-chain omega-3 fatty acids.

But—spoiler—it turns out there are some serious issues with the seafood industry, too.

In Hot Water

temperatures are rising, throwing off marine ecosystems' natural balance and kicking off negative ripple effects throughout their food chains. Overfishing—when we take fish out of their natural habitat at a rate too fast for them to keep up with in terms of replenishing the supply—has depleted wild populations of halibut, monkfish, tuna, and salmon, among others.

Salmon in particular are one of the most crucial species for the ecosystems they inhabit. Since they're born in freshwater streams but then migrate to the sea to mature, salmon serve as a link between saltwater and freshwater ecosystems, bringing nutrients from the oceans and vice versa. They're also a key food source for bigger animals like bears and whales.

But mass-producing salmon for human consumption has the species' wild population. Between the 1970s and , for example, the number of wild Atlantic salmon out there has been cut in half or maybe more, going from 8 to 10 million to just 3 to 4 million. And salmon farms have a recurring problem with parasites called sea lice (I know—gross), which flourish in densely-packed pens and spread to wild fish when farmed fish escape.

Fish Without Fish

A San Francisco-based startup called Wildtype is developing a product that could one day alleviate the problems caused by fish farming: the company is devoted to producing lab-grown salmon.

Similar to cultured meat like that made by Memphis Meats, Wildtype's salmon starts with real animal cells and adds a mixture of nutrients, sugars, salts, amino acids, and growth factor to coax the cells to grow as they naturally would inside an animal's body. Done right, the can yield animal tissue that contains muscle, blood, and fat, just like you'd get from a farmed fish. Except in some ways it's even better, because what you don't get is mercury, microplastics, and the other contaminants that farmed fish are becoming rife with.

Wildtype created its own technology for the “scaffolds” where tissue grows. “This is applicable to other species than the salmon that we have worked on,” Wildtype co-founder Arye Elfenbein told Tech Crunch. “We basically create a scaffold that provides the right guidance…for cells to take up fats in different places or become more striated.”

The company just opened up a pre-order waiting list for its product to chefs around the country, despite commercial production being up to five years away.

Challenges Upstream

Last year the company did a test for employees, investors, and a group of chefs and restaurateurs. While the texture of the fish was apparently realistic, its taste was described as “lacking.” And that's not the only challenge Wildtype will have to overcome; the company estimated that each spicy salmon roll served at the tasting cost $200 to produce.

This is the biggest issue with lab-grown meat, whether beef, pork, or fish—it's difficult and costly to scale up its production. Wildtype is aiming to lower its costs to seven to eight dollars a pound within a few years. “The dream vision is the cleanest, purest, freshest salmon, without contaminants or antibiotics, for a price lower than farmed Atlantic salmon,” said cofounder Justin Kolbeck.

It's likely that one day in the future—maybe distant, maybe not so much—we'll look back in disbelief at the way we used to raise and slaughter entire animals just to get a few cuts of their flesh. It will seem wasteful and barbaric to growing exactly the cuts of meat that we want, with no or pollution involved. It's still a ways off, but if companies like Wildtype can make their vision a reality, people, animals, and the planet will all be better off for it.

Democracy Is Ailing. Here’s How We Can Start Reviving It

democracy American flag borken

Masks. Vaccines. Immigration. . Gun control. Taxes. The list of divisive issues in American politics goes on, with liberals and conservatives seeming more polarized and less able to agree than ever before. Indeed, democracy is in a fragile state, not only in the US but around the world. What's gone wrong to get us into this sorry situation?

In an enlightening discussion last week at the Chicago Humanities Festival, two thought posited an unexpected response: it's not so much that we've messed things up—it's that we're in the midst of an unprecedented democratic effort, and there are bound to be some bumps in the road. Moreover, if we want the future to look bright instead of dim, we need to start working harder to bridge societal divides.

Yascha Mounk is a German-American political scientist, professor of International Affairs at Johns Hopkins University, senior fellow at the Council on Foreign Relations, and the author of four books, the most recent being The Great Experiment: Why Diverse Democracies Fall Apart and How They Can Endure.

Dr. Eboo Patel is the founder and president of Interfaith America, a Chicago-based international nonprofit that aims to promote interfaith cooperation. He's also the former faith advisor to and author of four books, most recently We Need to Build: Field Notes for Diverse Democracy.

According to House's 2021 ‘Freedom in the World' , the world has entered the 16th year of a democratic recession, and the international balance has shifted in favor of tyranny. What has caused democracy to become so fragile, and are we at some kind of precarious turning point?

Delicate Democracy

We've come to take it for granted that in relatively affluent countries like the US, Australia, Germany, or Japan, democracy will always be the chosen system of and is unlikely to come under serious threat. “I started worrying about whether that was really true, because I saw all these signs of fading democratic values,” Mounk said. “People participating less in civil society, the extremes rising, people being more open to populist leaders.” Take Trump in the US, Bolsonaro in Brazil, Modhi in India, or López Obrador in Mexico, to name a few.

This shift, in Mounk's opinion, has structural reasons, like a stagnation of living standards for middle- and working-class citizens, as well as a rise in internet and social media use, which pulls parties and issues to the extremes. “But it also has to do with the fact that we're trying to do something unprecedented right now,” he added. “We're trying to build religiously and ethnically diverse democracies that treat their members as equals.”

When democracies like Germany and the US were founded, they were to a large degree religiously and ethnically homogeneous. The US has become more diverse, but it doesn't have a history of treating different groups of citizens equally; one group got the power and influence while other groups were excluded.

There's a widespread pessimism in the US about the state of society—but, Mounk pointed out, building diverse democracies is extremely hard, and it's gone wrong multiple times in history. “If you understand that, you can look at the changes in US society over the last decade and have optimism,” he said. “Maybe not at a political level, but in the changes you see at the heart of our society. We are actually making real progress towards building these diverse democracies, and we'll continue to build on that in the coming decades.”

How's that for a breath of fresh air?

Crucial Civil Society

Patel's focus is on building civil society: athletic leagues, religious organizations or houses of worship, and other special interest or hobby groups where we spend time outside of our families. “Civil society is the place where people from diverse identities and divergent ideologies come together to engage in common aims and cooperative relationships,” Patel said. “This is the real genius of American society—you have a critical mass of institutions and spaces that bring people together for common aims, and the nature of the activity shapes cooperative relationships.”

Bringing people from different groups together to deepen trust and understanding is key. Groupishness, Mounk pointed out, is part of human nature, and that will never change—but we must manage it in a way that inspires cooperation and friendship rather than hatred, resentment, or violence.

He cited India as a thriving diverse democracy, but with periodic outbursts of violence between Hindus and Muslims. Studies have found that in villages and cities where there's less violence, there are more civic associations that unite people; Hindus and Muslims are both members of literature clubs, athletic clubs, volunteer organizations, etc. In places where violence more frequently breaks out, these associations still exist, but they keep Hindus and Muslims separate. It's no big surprise, then, that in moments when tensions are running high, the people in the first group of cities trust each other, while in the second, they don't feel like they know each other.

This second group, though, has been the rule throughout history; what we're trying to do now is the exception. “The rule of human history is that identity communities build institutions for their own identity communities to serve, grow, and reproduce them,” Patel said—and, when it comes down to it, to fight other communities.

A brilliance of diverse democracies, he added, is that groups can start institutions that are an expression of their identity—say, a Jesuit university or a Jewish volunteer organization—but serve people from any group. Patel's own father, an Indian Muslim, came to the US to attend the MBA program at Notre Dame—a private Catholic university—and that's why Patel is here .

“That's the secret sauce of America's democracy, and I think it's in danger,” he said. “We have to continue to build spaces out of our own identity expression that connect to other identities and have a stake in them thriving.”

Demography's Not Destiny

The US Census Bureau has predicted the US will be a “majority minority” country by 2045. If that's true, Mounk and Patel both said, we'd better start working harder to get away from the polarized, divisive political culture we're stuck in now.

“We're at a moment in America where liberals and conservatives don't agree on anything,” Mounk said. “But there's one thing they agree on, and it's wrong and dangerous: that's the idea that demography is destiny.” In his opinion this is far too simplistic, because the way different demographics vote can change over time.

Catholics and Irish Americans were key for Democrats in the 1960s, Mounk said, but today are one of the most reliable voter bases for . What made Trump competitive in the 2020 election was that he significantly increased his share of voters among every non-white demographic, from African-American to Asian-American to Hispanic. Biden ultimately won because he increased his share of white voters relative to Hillary Clinton's share from 2016. “We simply cannot predict who's going to be winning elections by running those numbers out into the future,” Mounk said. “And that's a good thing for our society, because I don't want to be able to look into this audience and know who you voted for by the color of your skin.”

Fixing the Future

Technology has done some to democracy, mainly through social media algorithms that amplify the most extreme voices at the expense of moderate, rational ones. What can tech do now to reverse this harm—and go beyond that to revitalize democracy, build meaningful connections between groups, and dial down political polarization?

Patel spoke of the importance of solution-minded entrepreneurs in helping heal social wounds. “A huge part of what makes our society healthy and vibrant is people standing up and saying ‘I'll solve that,'” he said. “Local solutions to local problems can have massive national implications.”

The democratization of technology, information, and knowledge means there's a greater proportion of people than ever before with access to tools that can catalyze positive change. We see people using tech to solve issues like homelessness, pollution, climate change, and even making existing digital technologies more ethical.

How can this spirit of community-oriented innovation be applied to fixing and preserving our ailing political system and bridging the many divides between citizens?

A line from Mounk's book reads, “Never in history has a democracy succeeded in being both diverse and equal, treating members of many different ethnic or religious groups fairly, and yet achieving that goal is now central to the democratic in countries around the world.”

Bitcoin’s Blowing Up, and That’s Good News for Human Rights. Here’s Why

Published

on

Bitcoin crypto money

Bitcoin's value reached an all-time high this after Tesla announced it had bought $1.5 worth of the . After its launch in early 2009, Bitcoin has gone through a lot of ups and downs. Some of its biggest price swings were in 2017 and 2018, when a steep rise followed by an 84 percent decline brought plenty of hype and headlines. After a quiet period, the last three months of 2020 saw yet another sharp rise as the currency's value more than tripled—and it's still climbing.

Not surprisingly, more and more investors are now jumping on what can still seem like a techy, trendy bandwagon. In an where governments are printing money hand over fist, people want a more secure place to put their assets. In addition to prevailing economic uncertainty, many institutional investors are dipping their toes into the cryptocurrency, and even PayPal began offering customers the ability to buy Bitcoin late last year. Elon Musk's repeated endorsement of the cryptocurrency hasn't , either. Some even believe digital currencies like Bitcoin are the future of money.

But intertwined with Bitcoin's more speculative potential (as an asset or currency) is an important feature many investors may miss: its power to protect human rights and stand against tyranny.

In a new for Reason magazine, Alex Gladstein, chief strategy officer at the Human Rights Foundation, explains why the cryptocurrency is an inalienable tool for preserving freedom, and how it's being used by people in different parts of the world to do so.

Money makes the world go 'round, and as such, it's a perfect tool for surveillance and control. The decline of cash in many societies and its replacement with digital payment methods means we've all but kissed financial privacy goodbye; all of our digital transactions are logged and kept on record for years.

In most democratic countries this doesn't tend to with consequences much more intrusive than targeted ads. But for the more than four billion people living under authoritarian regimes, it's a different story.

Their governments can—and do—freeze peoples' bank accounts, shut down ATMs, decide who gets cut off from financial services, and even seize private funds. Actions like these are often targeted at individuals labeled as problematic: activists, dissidents, union , critics of the ruling party, intellectuals, and the like. Cutting off access to money is a quick-and-dirty way to immobilize people, not to mention wreak havoc when it's done on a large scale.

If only there was a monetary system not controlled by a central bank, untouchable by governments, where value could be transmitted without corruption or interference and unaffected by international borders.

China Wants to Be the World’s AI Superpower. Does It Have What It Takes?

Published

on

red lantern on black China AI

China's star has been steadily rising for decades. Besides slashing extreme poverty rates from 88 percent to under 2 percent in just 30 years, the country has become a global powerhouse in manufacturing and technology. Its pace of growth may slow due to an aging population, but China is nonetheless one of the world's biggest players in multiple cutting-edge tech fields.

One of these fields, and perhaps the most significant, is artificial intelligence. The Chinese announced a plan in 2017 to become the world leader in AI by 2030, and has since poured billions of dollars into AI projects and research across academia, government, and private industry. The government's venture capital fund is investing over $30 in AI; the northeastern city of Tianjin budgeted $16 billion for advancing AI; and a $2 billion AI research park is being built in Beijing.

On top of these huge investments, the government and private companies in China have access to an unprecedented quantity of data, on everything from citizens' to their smartphone use. WeChat, a multi-functional app where people can chat, date, send payments, hail rides, read news, and more, gives the CCP full access to user data upon request; as one BBC journalist put it, WeChat “was ahead of the on the global stage and it has found its way into all corners of people's existence. It could deliver to the Communist Party a map of pretty much everybody in this country, citizens and foreigners alike.” And that's just one (albeit big) source of data.

Many believe these factors are giving China a serious leg up in AI development, even providing enough of a boost that its progress will surpass that of the US.

But there's more to AI than data, and there's more to progress than investing billions of dollars. Analyzing China's potential to become a world leader in AI—or in any technology that requires consistent innovation—from multiple angles provides a more nuanced picture of its strengths and limitations. In a June 2020 article in Foreign Affairs, Oxford fellows Carl Benedikt Frey and Michael Osborne argued that China's big advantages may not actually be that advantageous in the long —and its limitations may be very limiting.

Moving the AI Needle

To get an idea of who's likely to take the in AI, it could help to first consider how the technology will advance beyond its current state.

To put it plainly, AI is somewhat stuck at the moment. Algorithms and neural networks continue to achieve new and impressive feats—like DeepMind's AlphaFold accurately predicting protein structures or OpenAI's GPT-3 writing convincing articles based on short prompts—but for the most part these systems' capabilities are still defined as narrow intelligence: completing a specific task for which the system was painstakingly trained on loads of data.

(It's worth noting here that some have speculated OpenAI's GPT-3 may be an exception, the first example of machine intelligence that, while not “general,” has surpassed the definition of “narrow”; the algorithm was trained to write text, but ended up being able to translate between languages, write code, autocomplete images, do math, and perform other language-related tasks it wasn't specifically trained for. However, all of GPT-3's capabilities are limited to skills it learned in the language domain, whether spoken, written, or programming language).

Both AlphaFold's and GPT-3's success was due largely to the massive datasets they were trained on; no revolutionary new methods or architectures were involved. If all it was going to take to advance AI was a continuation or scaling-up of this paradigm—more input data yields increased capability—China could well have an advantage.

But one of the biggest hurdles AI needs to clear to advance in leaps and bounds rather than baby steps is precisely this reliance on extensive, task-specific data. Other significant challenges include the technology's fast approach to the limits of current computing power and its immense energy consumption.

Thus, while China's trove of data may give it an advantage now, it may not be much of a long-term foothold on the climb to AI dominance. It's useful for building products that incorporate or rely on 's AI, but not for pushing the needle on how artificially intelligent systems learn. WeChat data on users' spending habits, for example, would be valuable in building an AI that helps people save money or suggests items they might want to purchase. It will enable (and already has enabled) highly tailored products that will earn their creators and the companies that use them a lot of money.

But data quantity isn't what's going to advance AI. As Frey and Osborne put it, “Data efficiency is the holy grail of further progress in artificial intelligence.”

To that end, research teams in academia and private industry are working on ways to make AI less data-hungry. New training methods like one-shot learning and less-than-one-shot learning have begun to emerge, along with myriad efforts to make AI that learns more like the human brain.

While not insignificant, these advancements still fall into the “baby steps” category. No one knows how AI is going to progress beyond these small steps—and that uncertainty, in Frey and Osborne's opinion, is a major speed bump on China's fast-track to AI dominance.

How Innovation Happens

A lot of great inventions have happened by accident, and some of the world's most successful companies started in garages, dorm rooms, or similarly low-budget, nondescript circumstances (including Google, Facebook, Amazon, and Apple, to name a few). Innovation, the authors point out, often happens “through serendipity and recombination, as inventors and entrepreneurs interact and exchange ideas.”

Frey and Osborne argue that although China has great reserves of talent and a history of building on technologies conceived elsewhere, it doesn't yet have a glowing track record in terms of innovation. They note that of the 100 most-cited patents from 2003 to present, none came from China. Giants Tencent, Alibaba, and Baidu are all wildly successful in the Chinese market, but they're rooted in technologies or business models that came out of the US and were tweaked for the Chinese population.

“The most innovative societies have always been those that allowed people to pursue controversial ideas,” Frey and Osborne write. China's heavy censorship of the internet and surveillance of citizens don't quite encourage the pursuit of controversial ideas. The country's social credit system rewards people who follow the rules and punishes those who step out of line. Frey adds that top-down execution of problem-solving is effective when the problem at hand is clearly defined—and the next big leaps in AI are not.

It's debatable how strongly a culture of social conformism can impact technological innovation, and of course there can be exceptions. But a relevant historical example is the Soviet Union, which, despite heavy investment in science and technology that briefly rivaled the US in fields like nuclear energy and exploration, ended up lagging far behind primarily due to political and cultural factors.

Similarly, China's focus on computer science in its education system could give it an edge—but, as Frey told me in an email, “The best students are not necessarily the best researchers. Being a good researcher also requires coming up with new ideas.”

Winner Take All?

Beyond the question of whether China will achieve AI dominance is the issue of how it will use the powerful technology. Several of the ways China has already implemented AI could be considered morally questionable, from facial recognition systems used aggressively against ethnic minorities to smart glasses for policemen that can pull up information about whoever the wearer looks at.

Advertisement

This isn't to say the US would use AI for purely ethical purposes. The military's Project Maven, for example, used artificially intelligent algorithms to identify insurgent targets in Iraq and Syria, and American law enforcement agencies are also using (mostly unregulated) facial recognition systems.

It's conceivable that “dominance” in AI won't go to one country; each nation could meet milestones in different ways, or meet different milestones. Researchers from both countries, at least in the academic sphere, could (and likely will) continue to collaborate and share their work, as they've done on many projects to date.

If one country does take the lead, it will certainly see some major advantages as a result. Brookings Institute fellow Indermit Gill goes so far as to say that whoever leads in AI in 2030 will “rule the world” until 2100. But Gill points out that in addition to considering each country's strengths, we should consider how willing they are to improve upon their weaknesses.

While China leads in investment and the US in innovation, both nations are grappling with huge economic inequalities that could negatively impact technological uptake. “Attitudes toward the social change that accompanies new technologies matter as much as the technologies, pointing to the need for complementary policies that shape the economy and society,” Gill writes.

Will China's leadership be willing to relax its grip to foster innovation? Will the US business environment be enough to compete with China's data, investment, and education advantages? And can both countries find a way to distribute technology's economic benefits more equitably?

Time will tell, but it seems we've got our work cut out for us—and China does too.
