In fact, I find Django and Postgres to be the best solution for htmx but Go stack is probably almost as good in terms of developer velocity and obviously much faster. So I think that's a good solution.
You can really build powerful production apps with htmx, and what people underestimate is how good it is with AI assisted development (Claude understands it and does it well, and if any JS glue logic on a specific template is required, it's pretty well written and not a mess).
Go probably wins as a matter of trade-offs for pure productivity (speed, reliability, ease of refactor), but Java Spring Boot works excellently if you're willing to take the plunge (pretty steep learning curve), and the ecosystem really lends itself to building more complex stuff that holds for a while.
Rust is fun because it is an amazing multi-faceted language where agents will constantly deliver you working yet surprising implementations you'll have to quintuple check, and sometimes spend and afternoon trying to grok. The outcome is also perfectly usable, fast, and reliable, but developer velocity is lower.
Keep in mind of course that a lot of so called seniors were also producing mediocre code <insert framework or language here>. It doesn't change the point though.
Not a fan of java/spring boot, although kotlin is nice.
Currently all of my greenfield work projects are using alpine and tauri (rust). It's more complex than the django web apps, but already seeing strong performance gains and better runtime guarantees.
