Microsoft CEO says up to 30% of the company's code was written by AI

I can tell.

Sounds like this man dramatically underestimates how deep their codebase goes. Maybe 30% of what they write right now is written by AI,but I'd be shocked if 0.5% of Microsoft's code is written by AI.

Microsoft has been pumping out bad code made by bad human coders for half a century, and now they're pumping out bad code made by AI. That's progress!

This is implicitly a Lines of Code (LoC) metric, which is know in the software industry as a poor metric.

I can generate thousands of lines of inefficient code, or provide you a fine tuned, performant, product.
