How would that work? You'd type your question as a code comment maybe, and the IDE would do a Google search for you?
There's nothing automatic about StackOverflow.
StackOverflow suffered from the "benign neglect" variation of "enshittification" -- once they had a social game that people would play they did not attempt any kind of continuous improvement. Looking for answers involves:
1. Parsing a wordy question by a highly confused author to determine if their problem is really related to your problem.
2. Finding the accepted answer on top with 80+ upvotes and 10 comments that say "NOOOOOOOO! This is wrong!"
3. If it's Python the examples all look like
print x
In all the quality is atrocious and I think it's a better use of your time to read the manuals over and over again until you can find answers in the manual.
If generative AI coding assistant models were trained on StackOverflow, they already are using that data to autocomplete via inference.
