The other day I had it teach me some WebGL stuff. You always have to verify what it’s telling you, but I’m finding 95% of the time its knowledge is correct. It gives nice starting points for diving deeper into a topic.
I will say one thing it’s bad at: Writing SQL. Like awful; anything beyond a simple select statement becomes a huge, inefficient mess. I’d never have it write mutation statements just for data integrity reasons, but even simple read-only reports were a challenge for it.
