> All I hear about Claude, GPT, Gemini, etc., are how terrible they are, yet any discussion of Grok seems to always revolve around sensible, but confident, assertions that it's actually a great product and every new release is the point where Grok finally catches up.

Tesla self driving cars, (somewhat) as you say, but even the biggest proponents of Grok are like "oh no the best model is this, ugh".
