Artificial intelligence that is 10,000 times smarter than humans will be here in 10 years, SoftBank CEO Masayoshi Son said on Friday, in a rare public appearance during which he questioned his own purpose in life.

Son laid out his vision for a world featuring artificial super intelligence, or ASI, as he dubbed it.

The CEO first talked about another term — artificial general intelligence, or AGI — which broadly refers to AI that is smarter than humans. Son said this tech is likely to be one to 10 times smarter than humans and will arrive in the next three-to-five years, earlier than he had anticipated.

But if AGI is not much smarter than humans, "then we don't need to change the way of living, we don't need to change the structure of human lifestyle," Son said, according to a live translation of his comments in Japanese, which were delivered during SoftBank's annual general meeting of shareholders.

"But when it comes to ASI it's a totally different story. [With] ASI, you will see a big improvement."

Son discussed how the future will hold various ASI models that interact with each other, like neurons in a human brain. This will lead to AI that is 10,000 times smarter than any human genius, according to Son.

SoftBank shares closed down more than 3% in Japan, following the meeting.

Son is SoftBank's founder, who rose to prominence after an early and profitable investment in Chinese e-commerce giant Alibaba. He positioned SoftBank as a tech visionary with the 2017 launch of the Vision Fund, a massive investment fund focused on backing tech firms. While some of the bets were successful, there were also many high-profile failures, such as office sharing company WeWork.

After posting then-record financial losses at Vision Fund in 2022, Son said that SoftBank would go into "defense" mode and be more conservative with its investments. In 2023, the Vision Fund posted a new record loss, with Son shortly after saying that SoftBank would now shift into "offense," because he was excited about the investment opportunities in AI.

Son has been broadly out of the public eye since then.

He returned to the spotlight on Friday to deliver a speech that was full of existential questions.

"Two years ago, I am getting old, rest of my life is limited, but I haven't done anything yet and I cried so hard," Son said, suggesting he feels he hasn't achieved anything of consequence to date.

He added that he had now found SoftBank's mission, which is the "evolution of humanity." He also said he has discovered his own purpose in life.

"SoftBank was founded for what purpose? For what purpose was Masa Son born? It may sound strange, but I think I was born to realize ASI. I am super serious about it," Son said.
