What I don't get is people just blindly "following the hype" (as with anything else) and assuming it's a replacement for client side frameworks (react, vue, etc) for anything you might need out there. You already said this several times in some Podcasts I listen to, so I don't blame you. But people are just "hey bro just use HTMX and Go and done". And that might be fine if you're a backend developer that doesn't like JavaScript and have a very simple use case and probably don't have high UX standards or picky designers chasing you with every animation, loading state or performance issue.
There are many projects out there with pretty complex UX logic where this will just not work, and if it works the end result is going to be much harder to maintain. Let's not take into account finding people willing to work with these tools (already happened to us where we had to move a Rails/Hotwire project to Rails/Inertia) because no one could work on the frontend, initially created by a backend dev and that became such a mess not even him could maintain it anymore).
But again, it is not the technology to blame (it's great!), it is the usage of it. And people can misuse anything, as they misuse react/vue/etc when they're building just a landing page.
