AI is having its Nobel moment. Do scientists need the tech industry to
sustain it?

Hours after the artificial intelligence pioneer Geoffrey Hinton won a
Nobel Prize in physics, he drove a rented car to Google's California
headquarters to celebrate.
Hinton doesn't work at Google anymore. Nor did the longtime professor at
the University of Toronto do his pioneering research at the tech giant.
But his impromptu party reflected AI's moment as a commercial
blockbuster that has also reached the pinnacles of scientific
recognition.
That was Tuesday. Then, early Wednesday, two employees of Google's AI
division won a Nobel Prize in chemistry for using AI to predict and
design novel proteins.
“This is really a testament to the power of computer science and
artificial intelligence,” said Jeanette Wing, a professor of computer
science at Columbia University.
Asked about the historic back-to-back science awards for AI work in an
email Wednesday, Hinton said only: “Neural networks are the future.”
It didn't always seem that way for researchers who decades ago
experimented with interconnected computer nodes inspired by neurons in
the human brain. Hinton shares this year's physics Nobel with another
scientist, John Hopfield, for helping develop those building blocks of
machine learning.
Neural network advances came from “basic, curiosity-driven research,”
Hinton said at a press conference after his win. “Not out of throwing
money at applied problems, but actually letting scientists follow their
curiosity to try and understand things.”
Such work started well before Google existed. But a bountiful tech
industry has now made it easier for AI scientists to pursue their ideas
even as it has challenged them with new ethical questions about the
societal impacts of their work.
One reason why the current wave of AI research is so closely tied to the
tech industry is that only a handful of corporations have the resources
to build the most powerful AI systems.
“These discoveries and this capability could not happen without
humongous computational power and humongous amounts of digital data,”
Wing said. “There are very few companies — tech companies — that have
that kind of computational power. Google is one. Microsoft is another.”
The chemistry Nobel Prize awarded Wednesday went to Demis Hassabis and
John Jumper of Google’s London-based DeepMind laboratory along with
researcher David Baker at the University of Washington for work that
could help discover new medicines.
Hassabis, the CEO and co-founder of DeepMind, which Google acquired in
2014, told the AP in an interview Wednesday his dream was to model his
research laboratory on the “incredible storied history” of Bell Labs.
Started in 1925, the New Jersey-based industrial lab was the workplace
of multiple Nobel-winning scientists over several decades who helped
develop modern computing and telecommunications.
“I wanted to recreate a modern day industrial research lab that really
did cutting-edge research,” Hassabis said. “But of course, that needs a
lot of patience and a lot of support. We’ve had that from Google and
it’s been amazing.”
Hinton joined Google late in his career and quit last year so he could
talk more freely about his concerns about AI’s dangers, particularly
what happens if humans lose control of machines that become smarter than
us. But he stops short of criticizing his former employer.
Hinton, 76, said he was staying in a cheap hotel in Palo Alto,
California when the Nobel committee woke him up with a phone call early
Tuesday morning, leading him to cancel a medical appointment scheduled
for later that day.

By the time the sleep-deprived scientist reached the Google campus
in nearby Mountain View, he “seemed pretty lively and not very tired
at all” as colleagues popped bottles of champagne, said computer
scientist Richard Zemel, a former doctoral student of Hinton’s who
joined him at the Google party Tuesday.
“Obviously there are these big companies now that are trying to cash
in on all the commercial success and that is exciting,” said Zemel,
now a Columbia professor.
But Zemel said what’s more important to Hinton and his closest
colleagues has been what the Nobel recognition means to the
fundamental research they spent decades trying to advance.
Guests included Google executives and another former Hinton student,
Ilya Sutskever, a co-founder and former chief scientist and board
member at ChatGPT maker OpenAI. Sutskever helped lead a group of
board members who briefly ousted OpenAI CEO Sam Altman last year in
turmoil that has symbolized the industry's conflicts.
An hour before the party, Hinton used his Nobel bully pulpit to
throw shade at OpenAI during opening remarks at a virtual press
conference organized by the University of Toronto in which he
thanked former mentors and students.
“I’m particularly proud of the fact that one of my students fired
Sam Altman,” Hinton said.
Asked to elaborate, Hinton said OpenAI started with a primary
objective to develop better-than-human artificial general
intelligence “and ensure that it was safe.”
"And over time, it turned out that Sam Altman was much less
concerned with safety than with profits. And I think that’s
unfortunate,” Hinton said.
In response, OpenAI said in a statement that it is “proud of
delivering the most capable and safest AI systems” and that they
“safely serve hundreds of millions of people each week.”
Conflicts are likely to persist in a field where building even a
relatively modest AI system requires resources “well beyond those of
your typical research university,” said Michael Kearns, a professor
of computer science at the University of Pennsylvania.
But Kearns, who sits on the committee that picks the winners of
computer science's top prize — the Turing Award — said this week
marks a “great victory for interdisciplinary research” that was
decades in the making.
Hinton is only the second person to win both a Nobel and Turing. The
first, Turing-winning political scientist Herbert Simon, started
working on what he called “computer simulation of human cognition”
in the 1950s and won the Nobel economics prize in 1978 for his study
of organizational decision-making.
Wing, who met Simon in her early career, said scientists are still
just at the tip of finding ways to apply computing's most powerful
capabilities to other fields.
“We’re just at the beginning in terms of scientific discovery using
AI,” she said.
