In the tech market, 2021 was a 12 months of earnings and pivots.

Thanks in element to the pandemic and the digitization of our lives, all of the significant tech firms received even bigger. Fb adjusted its title to Meta, Jeff Bezos went to place, Jack Dorsey left Twitter and Silicon Valley fell harder for crypto.

Each December, partly to cheer myself up right after a yr of covering tech’s scandals and shortfalls, I use this column to elevate up a handful of tech assignments that enhanced the globe all through the year. My criteria are rather unfastened and arbitrary, but I glance for the forms of deserving, altruistic initiatives that use know-how to massive, societal challenges, and that do not get considerably attention from the tech push, like start out-ups that are making use of synthetic intelligence to combat wildfires, or food items-delivery applications for the needy.

Particularly at a time when lots of of tech’s leaders seem extra intrigued in making new, digital worlds than enhancing the environment we live in, it’s worthy of praising the technologists who are stepping up to address some of our most significant problems.

So in this article, with no even further ado, are this year’s Superior Tech Awards.

1 of the year’s most fascinating A.I. breakthroughs arrived in July when DeepMind — a Google-owned synthetic intelligence enterprise — published info and open up-source code from its groundbreaking AlphaFold task.

The challenge, which employed A.I. to predict the structures of proteins, solved a problem that experienced vexed scientists for a long time, and was hailed by specialists as 1 of the greatest scientific discoveries of all time. And by publishing its details freely, AlphaFold established off a frenzy amongst researchers, some of whom are already utilizing it to create new prescription drugs and greater realize the proteins concerned in viruses like SARS-CoV-2.

Google’s all round A.I. initiatives have been fraught with controversy and missteps, but AlphaFold appears to be like an unequivocally superior use of the company’s large experience and sources.

Men and women love feeding on meat. But the industrial-farm procedure that creates the huge the vast majority of the world’s meat provide is an moral and environmental catastrophe, and plant-based substitutes haven’t caught on extensively with carnivores. Consequently the significance of cultured meat — which is grown from cells in a lab, fairly than taken from slaughtered animals, and which may well be tech’s response to our global meat addiction.

Despite much more than a decade of research and growth, cultured meat is even now considerably as well high-priced and really hard to make. But that may well be modifying quickly, many thanks to the attempts of dozens of commence-ups such as Upside Food items, Mosa Meat and Wildtype.

Upside Food items, previously known as Memphis Meats, opened a 53,000-square-foot plant in California this year, and declared it had figured out a way to improve cells into meat with no applying animal elements.

Mosa Meat, a Dutch cultivated-meat get started-up, announced important breakthroughs in its engineering, far too, like a process of increasing animal body fat that is 98 per cent less costly than the past approach.

And Wildtype, a San Francisco commence-up that is creating lab-grown seafood, produced a new, mobile-primarily based salmon item this year that is receiving excellent evaluations in early tests, even nevertheless the Food and Drug Administration has not nevertheless approved it.

Prisons are not recognised as hotbeds of innovation. But two tech jobs this yr tried out to make our prison justice method much more humane.

Recidiviz is a nonprofit tech start-up that builds open up-supply data tools for legal justice reform. It was started off by Clementine Jacoby, a former Google worker who noticed an chance to corral details about the jail process and make it out there to prison officials, lawmakers, activists and researchers to notify their decisions. Its equipment are in use in 7 states, which include North Dakota, where the information instruments served jail officials assess the possibility of Covid-19 outbreaks and establish incarcerated individuals who were being eligible for early launch.

Ameelio, a nonprofit start-up founded by two Yale pupils and backed by tech honchos like Jack Dorsey and Eric Schmidt, is striving to disrupt jail communications, a notoriously exploitative marketplace that rates inmates and their loved types exorbitant service fees for telephone and movie phone calls. This calendar year, it introduced a totally free online video contacting provider, which is staying analyzed in prisons in Iowa and Colorado, with ideas to insert additional states up coming calendar year.

When I initially read about experimental initiatives to 3-D print residences a several yrs back, I dismissed them as a novelty. But 3-D printing know-how has enhanced steadily considering that then, and is now remaining utilised to create true houses in the United States and overseas.

3-D printing homes has numerous positive aspects: It’s drastically more affordable and faster than classic construction (houses can be 3-D printed in as small as 24 several hours), and they can be manufactured using local products in pieces of the planet in which concrete is challenging to come by.

ICON, a development know-how firm based mostly in Texas, has 3-D printed a lot more than two dozen buildings so significantly. Its technological know-how was made use of to print properties in a village in Mexico this yr, and the firm ideas to break ground up coming yr on a progress in Austin, Texas, that will consist fully of 3-D printed houses.

Mighty Properties, dependent in Oakland, Calif., is having a a little unique approach. It sells prefab home kits consisting of 3-D printed panels that are manufactured in a manufacturing facility and assembled on site. Its properties are powered by photo voltaic panels and loaded with electricity-productive features, and it not long ago struck a offer to 3-D print 15 residences in a subdivision in Rancho Mirage, Calif.

Our countrywide housing crisis, it must be claimed, is not mostly a tech challenge. Bad zoning and tax legislation, NIMBY protectionism and other elements have played a portion in building housing unaffordable for quite a few. But it’s comforting to know that if and when area and condition governments get their acts with each other and start out making much more housing, 3-D printing could enable velocity up the procedure.

Few tech tales produced as big an influence this yr as the revelations from Frances Haugen, the Facebook product or service supervisor turned whistle-blower who was the principal supply for The Wall Avenue Journal’s blockbuster “Facebook Information” collection. By creating community 1000’s of paperwork detailing internal Facebook investigate and discussions about the platform’s harms, Ms. Haugen sophisticated our collective understanding about Facebook’s internal workings, and her congressional testimony was a landmark second for tech accountability.

Shortly right after Ms. Haugen went public, two previous users of Facebook’s integrity team, Jeff Allen and Sahar Massachi, began the Integrity Institute, a nonprofit that is intended to help social media corporations navigate thorny problems about rely on, protection and system governance. Their announcement received a lot less consideration than Ms. Haugen’s document dump, but it is all aspect of the identical worthy effort and hard work to educate lawmakers, technologists and the general public about creating our social media ecosystem much healthier.

Ms. Scott, who acquired divorced from Jeff Bezos in 2019, did not introduce new know-how or a start out-up in 2021. But she is giving absent her Amazon fortune — approximated to be worthy of more than $50 billion — at a rate that makes other tech philanthropists look like penny pinchers.

She donated much more than $6 billion in 2021 by yourself to a host of charities, schools and social applications, an astonishing feat for an unique doing the job with a modest workforce of advisers. (For scale, the entire Gates Foundation gave out $5.8 billion in direct grants in 2020.)

And not like other donors, who splash their names on buildings and museum wings, Ms. Scott introduced her gifts quietly in a collection of understated website posts. Let’s hope that in 2022, extra tech moguls follow her lead.
