> But do you think this is our first rodeo with "XYZ has fundamentally shifted things and startups now start up faster"? RoR did the same, Bootstrap as well, and countless of other things.

I really don't understand anyone who can say something like this with a straight face. Comparing AI to Bootstrap? I...

Both have sped up front end development at the cost of making half of the internet look the same.

I don't think it's fair to blame AI just because people aren't prompting unique design elements into their vibe-coding.

Doing that would negate productivity gains for the users that prompt it for things outside their expertise.

I'm not convinced it would be completely negated... maybe slowed down a bit, but sure.

It must be some sort of denial playing into this

That seems like comparing the internet to jQuery.

Only if you're actively inside of the hype-machine and don't see it from the outside with the experience of previously having been inside of the hype-machine.

No. RoR lets you build a certain class of web apps faster. AI lets you build almost anything faster.

Again, I'm not bashing AI and I'm much more productive with AI myself too, no need to try to defend something I'm not attacking...

I'm not defending AI, I'm attacking your logic.

The logic was/is "other topics been popular on the HN frontpage in the past and their advocates have made bunch of claims about their topics, and eventually it'll die down too, like the others did", that's hardly under attack here as you're on some wild tangent right now.
