TOKYO, Oct 29 (Reuters) - SoftBank Group CEO

Masayoshi Son reiterated his belief in the coming of artificial

super intelligence (ASI) on Tuesday, saying it would require

hundreds of billions of dollars of investment to realise.

Artificial super intelligence will be 10,000 times smarter

than a human brain and will exist by 2035, Son told an audience

of global business, technology and finance leaders at a

conference in Riyadh, Saudi Arabia.

Son said he is saving up funds "so I can make the next big

move," but did not provide any details as to his investment

plans.

He predicted that generative AI will require $900 trillion

dollars in cumulative capital expenditure in data centres and

chips in the future, adding that he thought chip maker Nvidia ( NVDA )

was undervalued on this basis.

Son has long touted the promise of new technologies and

made his name and fortune on successful bets on the

proliferation of mobile internet and e-commerce.

However, his record as an investor is patchy. The launch of

SoftBank's mammoth Vision Fund investment vehicles from 2017

upended the world of venture capital but many of the funds' high

growth startups have crashed in value.

The funds were down $2.4 billion in aggregate as of the end

of June 2024.

Saudi Arabia's sovereign wealth fund PIF invested $45

billion into the first Vision Fund.
