I typically reach for Go when I am building things, bubbletea, a TUI library uses the Elm architecture and enforces it on people using it.

Did not like, Won't use again.

MVC is well understood and works perfectly in my experience.

IMO the ELM architecture only works with pure functions. It doesn't work with languages which cannot provide this compile time guarantee. Also functional programming needs a different mindset / training. You won't benefit from it until you understand what it actually brings to the table (and what it leaves out).

I have to ask - I like some of the paradigms of Functional programming (IMO it makes concurrent programming a lot easier because state is never shared)

Why hasn't it cut through, like OO did?

Beam has been around since the 90s, had a good marquee project (RabbitMQ) but still has low adoption

I am not sure I if I can speak to that in general but personally I discovered functional programming late. Object oriented programming was all the rage when I got initiated and that is all that was taught in colleges.
