It'll be really hard to measure this because you can't easily isolate the impact of LLMs vs all the economy. I guess anything at all will overshadow LLMs numbers (e.g. tiny changes in Fed interest rates having more impact on job posts than LLMs ever will).

I only have anecdata to share. My coworkers and friend seem to be going through the disillusionment phase and finding LLMs as a better (if mildly outdated) search engine and a helper for simple well-known tasks. I guess the 10% productivity improvement makes sense from what I've seen.

I've also met company owners that thought they could reduce their workforce drastically because of LLMs. I can only wish them good luck, it's going to be bumpy for them once they realize the mess they will be in (e.g. spending more time troubleshooting systems their engineers never understood in the first place).

TL;DL; No, except for places you wouldn't want to work at.
