Second this. From using LLM within my daily IC workflow, its not that developers are getting a productivity boost, its that our job became more enjoyable. I didn't even realize how much frustration builds up over time while relying on google search for things such as that one obscure api method i forgot the name of. I have to dig and dig...
Somehow using GPT in its place has brought a noticeable bump to my quality of life. Most of my dev colleagues share this sentiment.
Impact on the tech economy from this? Unknown.
