Emad Mostaque, 40, who founded Stability AI three years ago, said this could happen in a “worst case scenario” and humans could be told “goodbye, you’re kind of boring”.
However, governments could soon be shocked into regulating the machines by an event that suddenly makes their impact real, he added.
In an interview with the BBC’s Laura Kuenssberg On Sunday programme, he said: “If you have a more capable thing than you, what is democracy in that kind of environment?
“This is a known unknown because we can’t conceive of something more capable than us but we all know people more capable than us.
“My personal belief is that it will be like that movie Her with Scarlett Johansson and Joaquin Phoenix, humans are a bit boring and it will be like ‘goodbye, you’re kind of boring’, but I could be wrong.
“It deserves to be discussed in a public sphere, if we have agents more capable than us that we cannot control, that are going across the internet and hooked up and they achieve a level of automation, what does that mean?
“The worst case scenario is that it proliferates and basically it controls humanity because you could have a million things replicating effectively, but we don’t know.”
He believes the moment that actor Tom Hanks caught coronavirus in March 2020 was the moment millions understood the risk of the novel disease.
When a similar moment arrives with artificial intelligence governments will conclude “we need policy now”, he said.
The impact of the new machines could be “painful” to begin with and their effect on the economy could be greater than that caused by the pandemic, he believes.
However, he thinks the jobs which disappear will be replaced by better ones because machines will do menial tasks, allowing us to concentrate on the things which make us human.
