Silly premise and vapid article. Tailwind 'won' in the same way Bootstrap 'won', i.e. it was popular for a time. $10 says Tailwind will be the Bootstrap of 2027.
Kind of the same with jquery (although it took quite a lot of new stuff...)
I feel like Tailwind won't get that
Components UI systems are not going away, even as we move back to static heavy sites and minimizing JS where ever possible.
The key difference between Bootstrap and Tailwind is that Tailwind designs are distributed. So Bootstrap designs feel like Bootstrap designs, while for Tailwind you can keep having new and fresh designs from different sources.
