> basically unusable for anything except very technical things

It's problematic here. I use it as a kind of search engine for technical questions occasionally, but it's only safe to do so as I know the subjects I'm asking about, eg. bash scripts, database details, and so on.

It's often useful in synthesising information for these sorts of things, but its ability to talk nonsense means you have to be on your guard and know the territory.
