But Rust has little to do with what Ruby/Rails is used for, and Python is mostly used in other fields also (it's not like Django is taking over the world). Every time I look at the various JS frameworks it seems like just a huge lift to get something going versus Rails, for typical SME type business problems. Most problems don't really seem to require SPA.
Things like Elixir/Phoenix look very interesting and promising, but their ecosystem is (for now) much smaller. And just the size of the Elixir community right now suggests that it's not like all the RoR developers went to Elixir.
So what is the thing that is so much more attractive than Rails, to solve your everyday business logic issues for small to medium scale problems?
Does all engineers and companies think they are solving Google-scale problems or something?
I feel like I'm missing something obvious.
