I didn't intend to argue either way, but I feel that adding "and search" to the argument made above doesn't really weaken it. The full claim is that regular users weren't really interested in using power-user apps, so they won't be interested with a chat-bot UI either.

I do personally think that we'll see regular users interested in new, different workflows than the automation ones we associate with power users, and the image generation use case you mention is a good example. Chat-bots do seem to be owning those rather than entirely new apps.
