I think it'll still be obvious, considering how "ABSOLUTE FINAL ULTIMATE TOTAL NUCLEAR" AI tends to end up when it goes off rails. This is going to have problems. Have you ever been stuck on a long customer service call in which the first solution didn't work? Now imagine those calls handled by AI, which tends to go insane when it concludes it's failed at a task.
Supposedly the selling point here is the infinite patience, aside from the whole not demanding a salary thing. But I am skeptical. I have not talked with Grok (I just take screenshots) but I have had Gemini lose its patience with me while doing tech support. It gave me multiple suggestions, and it decided that it liked its first (and most drastic, naturally) suggestion best. I had legitimate reasons why I needed to save it for a last resort, but as I probed at other options it started playing the "Per my first answer" card until it spat a bunch of links at me and ended the conversation.
