What do you use now?

I work in IT and between the Advent of "agile" methodologies meaning lots of documentation is out of date as soon as it's approved for release and AI results more likely to be invented instead of regurgitated from forum posts, it's getting progressively more difficult to find relevant answers to weird one-off questions than it used to be. This would be less of a problem if everything was open source and we could just look at the code but most of the vendors corporate America uses don't ascribe to that set of values, because "Mah intellectual properties" and stuff.

Couple that with tech sector cuts and outsourcing of vendor support and things are getting hairy in ways AI can't do anything about.
