Updated my comment to include the link. As much as 30% specifically generated by AI.

The 2nd paragraph contradicts the title.

The actual quote by Satya says, "written by software".

Sure but then he says in his next sentence he expects 50% by AI in the next year. He’s clearly using the terms interchangeably.

I would still wager that most of the 30% is some boilterplate stuff. Which is ok. But sounds less impressive with that caveat.
