"Fancy autocomplete" doesn't seem very scathing when the autocomplete you're talking about is "give me feedback and find bugs in this 3000 line file: <paste>".

Ah yes, it's just using pattern recognition from its training data to generalize abstract concepts about software so that it can apply them to my specific, complex file to find a bug that eluded multiple software engineers for a month.

It's a stochastic parrot!
