Programming

I agree. And those decades of development come with huge advantages. Libraries. Patterns. Textbooks! Billions of lines of code you can cross reference and learn from!

It's fun to bleed a little when you are tinkering. It's not fun to have to reinvent the wheel because you choose a language that doesn't have an existing ecosystem. That becomes and chicken-and-egg problem. The tinkerers fulfill this role (building out the ecosystem) and also tend to advocate for their tinkering language of choice. But there needs to be a real critical mass.

It takes decades to shift an entrenched ecosystem. Check in ten years if the following exist in languages other than C/C++: an enterprise grade database, a python(/etc.) interpreter that isn't marked experimental, an OS kernel that is used somewhere real, an embedded manufacturer that ships the language as its first class citizen, a AAA game using it under the engine...

Like, in the last 15 years, I'm only aware of a single AAA game that used a memory safe language -- Neverwinter Nights 2 used C# for part of the Electron Engine...

Rust is the most likely candidate here, although you see things like Erlang being used to make some databases (CouchDB). People see Rust being used on some real infrastructure projects that gain actual traction (polars comes to mind). Polars is an interesting use case though -- it's simply better than the other projects in its particular space and so people are switching to it not because it is written in rust at all... And honestly, that's probably the only way this happens.
