You could, but Grok is pretty high up there, it might not be "#1" but its definitely up there with the giants, people seem to overlook it. Gemini has a similar problem, it was #1 once, and it seems like Google isn't hell bent on chasing #1 they just want to keep iterating over time, they know they just need it to be "good enough" and they'll keep having repeat customers.

If Elon REALLY wanted to do anything like that he would be better off poaching talent from competitors, less legal hell to go through.
