This is completely wrong, all this pages are mine and are Tailwind:

https://berrus.app/ (game) https://josepvidal.dev/ (my site) https://fescims.com/ (mountaineering community)

Even my mobile app for the mountaineering community is tailwind (Yes, there is Tailwind for ReactNative): https://apps.apple.com/us/app/cims-mountain-challenges/id674...

My point being, quick AI slop landing pages and products will share the same vibes, but at the end Tailwind is just a collection of css classnames, allowing you to build and create as much as cool and unique pages as with plain css if you put the effort.
