I like how Yaron Minsky from Jane Street characterized it: “It is smarter than we expected to be but dumber than it needed to be… It feels like something really dumb but somehow memorized the entire internet.”

This is kind of what I feel: despite all these impressive BAR and IMO achievements, in my work, I feel they do a great job at parapherasing the internet, but fails when you need it to do something mildly intelligent.

Does it improve my efficiency? yes, but only at some very tedious and specific taskes, once I go slightly out of scope, it comes up with inelegant solution that I will need to rewrite from scratch.
