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.
Well, not exactly productivity, but yes there are some symptoms of a reduction in quality from some companies. I was about to say not the three mentioned, but GitHub (owned by Microsoft) is certainly one, and Amazon seems to be having an uptick in outages that are anecdotally linked to use of AI. Anthropic, who we know are using AI a lot internally also have reliability problems.
