Artificial intelligence pioneer Geoffrey Hinton says it香蕉视频直播檚 getting more difficult to tell videos, voices and images generated with the technology from material that香蕉视频直播檚 real 香蕉视频直播� but he has an idea to aid in the battle.

The increased struggle has contributed to a shift in how the British-Canadian computer scientist and recent Nobel Prize recipient thinks the world could address fake content.

香蕉视频直播淔or a while, I thought we may be able to label things as generated by AI,香蕉视频直播� Hinton said Monday at the inaugural Hinton Lectures.

香蕉视频直播淚 think it香蕉视频直播檚 more plausible now to be able to recognize that things are real by taking a code in them and going to some websites and seeing the same things on that website.香蕉视频直播�

He reasons this approach would verify content isn香蕉视频直播檛 fake and imagines it could be particularly handy when it comes to political video advertisements.

香蕉视频直播淵ou could have something like a QR code in them (taking you) to a website, and if there香蕉视频直播檚 an identical video on that website, all you have to do is know that that website is real,香蕉视频直播� Hinton explained.

Most Canadians have spotted deepfakes online and almost a quarter encounter them weekly, according to an April survey of 2,501 Canadians conducted by the Dais, a public policy organization at Toronto Metropolitan University.

Deepfakes are digitally manipulated images or videos depicting scenes that have not happened. Recent deepfakes have depicted Pope Francis in a Balenciaga puffer jacket and pop star Taylor Swift in sexually explicit poses.

The Hinton Lectures are a two-night event the Global Risk Institute is hosting this week at the John W. H. Bassett Theatre in Toronto.

The first evening saw Hinton, who is often called the godfather of AI, take the stage briefly to remind the audience of the litany of risks he香蕉视频直播檚 been warning the public over the last few years that the technology poses. He feels AI could cause or contribute to accidental disasters, joblessness, cybercrime, discrimination and biological and existential threats.

However, the bulk of the evening was dedicated to a talk from Jacob Steinhardt, an assistant professor of electrical engineering and computer sciences and statistics at UC Berkeley in California.

Steinhardt told the audience he believes AI will advance even faster than many expect but there will be surprises along the way.

By 2030, he imagines AI will be 香蕉视频直播渟uperhuman,香蕉视频直播� when it comes to math, programming and hacking.

He also thinks large language models, which underpin AI systems, could become capable of persuasion or manipulation.

香蕉视频直播淭here is significant headroom, if someone were to try to train (them) for persuasiveness, perhaps either an unscrupulous company or a government that cared about persuading its citizens,香蕉视频直播� Steinhardt said. 香蕉视频直播淭here香蕉视频直播檚 a lot of things you could do.香蕉视频直播�

He told the audience he sees himself as a 香蕉视频直播渨orried optimist,香蕉视频直播� who believes there香蕉视频直播檚 a 10 per cent chance the technology will lead to human extinction and a 50 per cent chance it will cause immense economic value and 香蕉视频直播渞adical prosperity.香蕉视频直播�

Asked at a later news conference about Steinhardt香蕉视频直播檚 香蕉视频直播渨orried optimist香蕉视频直播� label, Hinton called himself a 香蕉视频直播渨orried pessimist.香蕉视频直播�

香蕉视频直播淭here香蕉视频直播檚 research showing that if you ask people to estimate risks, normal, healthy people way underestimate the risks of really bad things 香蕉视频直播� and the people who get the risks about right are the mildly depressed,香蕉视频直播� Hinton said.

香蕉视频直播淚 think of myself as one of those, and I think the risks are a bit higher than Jacob (Steinhardt) thinks, let香蕉视频直播檚 say around 20 per cent.香蕉视频直播�

Hinton also used the news conference to share more about what he has done with his half of the 11 million Swedish kronor (about C$1.45 million) he and Princeton University researcher John Hopfield received when they won the Nobel Prize for physics earlier in the month.

Hinton said he has donated half his share of the award to Water First, a Creemore, Ont., organization training Indigenous communities in how to develop and provide access to safe water systems.

He initially mulled giving some of the money to a water organization actor Matt Damon is involved with in Africa, but then he said his partner asked him 香蕉视频直播淲hat about Canada?香蕉视频直播�

That led Hinton to discover Water First. He said he was compelled to donate to it because of the land acknowledgements he hears at the start of many events.

香蕉视频直播淚 think it香蕉视频直播檚 great that they香蕉视频直播檙e recognizing (who lived on the land first), but it doesn香蕉视频直播檛 stop Indigenous kids getting diarrhea,香蕉视频直播� he said.

Hinton previously said some of his winnings will also be directed to an organization that provides jobs to neurodiverse young adults.
