“That number in our world today is like meaningless, in the sense that every part of code we now touch is influenced by AI deeply.”

Asked what share of Google's code is now written by AI (he had put it at 25% the year before), Pichai says the metric no longer means much. Google now tracks other numbers instead, such as more code changes and fewer rollbacks since launching its internal coding tool.

…is a challenging project. The team has disciplined milestones, and so it was a super exciting milestone to send the TPUs up to space. And sometime as we are speaking, we are expecting a hello world moment from them. And so I look forward to seeing that happen. And we'll continue investing here too.
You recently, was it maybe last year you said that 25% of code written within Google was written by AI? What's the number today?
I mean, we have far, I think we've almost, that number in our world today is like meaningless in the sense that every part of code we now touch is influenced by AI deeply. What's now what we are tracking with Argon, for example, we are now able to see. It's been a point of inflection. People are using Argon to really go tackle complex projects, right? And including projects which affects millions of lines of code. So we have definitely, in the four weeks since we've launched Orgon, we have seen a 30% increase in CLs and more importantly, almost a similar increase, one-third decrease in rollbacks, right? And so I think people are writing code more productively and better code with it, code with it. So I think we are tracking it with newer metrics now.
Talking about the opposition to data centers and how do you feel that? And if you can't build data centers in the US the way that you want to, where else do you go?
We're very committed to. Building our data centers very responsibly. I think when I look at our largest data centers in some of the communities where we have been the longest, I visit them, I talk to people, there are people who would come and tell us their kids have gone to college because of our…
have been surprised by data centers showing up in their backyard.
