Software written in Big tech companies is probably written at 90% with AI.

Now you could claim that software from Google/Meta/Microsoft is useless, but billions of humans rely on it every day.

I highly doubt that, unless you are talking about something much more specific like test cases.

There is certainly no sign of these companies becoming more productive.

Most of the software that "billions" of humans are relying from any of these companies are things like Microsoft Windows, Microsoft Office, Google Search, FaceBook, that were not written, or rewritten, in last 1-2 years, so were certainly not written by AI.

Oh, if you look at real signs, like uptime and number of bugs, they are becoming very clear.

But it's not clear how much of it is caused by the layoffs and how much is because of LLMs.
