Hello and welcome to NewsHour.
It's coming to you live from the BBC World Service Studios in central London.
I'm Tim Franks.
And we're beginning the programme with one of the most powerful men on the planet.
And he's talking about an issue which could affect us all.
And that is not hyperbole, me overstating the case on either count.
Because the person I'm talking about is the CEO of Google,
Sundar Pichai, the boss of the company which is the portal to...
so much of what we do on the internet.
And the issue is what people are referring to as the artificial intelligence bubble,
the super-inflated stock market valuation of AI companies into which companies such as Google have poured hundreds of billions of dollars of investment.
The widely predicted fear is that when, and it's increasingly seen as when not if,
that bubble bursts, the whole global economy could judder into a downturn.
So hearing what Sundar Pichai has to say, especially about AI, matters.
He's been speaking exclusively to the BBC's economics editor Faisal Islam in the heart of Silicon Valley in Mountain View,
California.
Every decade or so, you know, you have this inflection points.
You have a new technology.
It was a personal computer at one point, the internet coming in the late 90s.
Then it was mobile.
