And my answer - like the best of car mechanics who work on custom rides - is: I don't know how long until I actually get in there, but minimum 5x what you think, and my rate is $300/hr. Is it worth it to you to do it right?
Usually the answer is no. When it's yes, I have a free hand. And having a few clients who pay well is worth a lot more than having a few dozen who think they know everything and are too cheap to pay for it anyway.
I've never seen an LLM proclaim anyone to be an expert unabetted, alone the leading expert globally. And on the other side of the coin, very few people are willing to believe an obvious sycophant making claims of their greatness they themselves don't even believe.
I don't want to forego addressing your point though, and yeah, Kalanick seems to be one of the people delusional enough to believe what the bots tell him. That said, I'd argue that even then, it isn't the LLM that's puffing up his ego, it's actually his self-aggrandizing interpretation of the interaction. I doubt Grok was fawning over him and telling him he's was the smartest specialist physicist out there.

And regex.
Part of the issue is that it is so fast to get to a working prototype that it feels like you are almost there, but there is a lot of effort to go.
People made tools specifically to make templates look like templates and not a finished product, just because client was ready to push the product just after seeing real looking mockups of interface.
Not too different in that respect from non-AI-assisted coding! The "last 10%" is always more like 50-80%.
