Matt Godbolt sold me on Rust by showing me C++

My admittedly uninformed impression of Rust is that its a lot like Go (in spirit?), a language invented to shepherd novice programmers into not making mistakes with resource usage.

I imagine faceless shameless mega-corps with thousands of Rust/Go peons coding away on the latest soulless business apps. Designed to funnel the ignorant masses down corridors of dark pattern click bait and confusing UX.

Having exposed my biases, happy to be proven wrong. Why are game studios still using C++? Because that's the language game programmers know and feel comfortable with? Or some other reason?

Embedded is still C, games are C++, scientific and data are Python and R (I'm talking in general here). What is the niche for Rust?

Novice programmers will take longer to be productive in Rust compared to Go. Rust primarily improves the productivity of people who know what they are doing, because it gives them much better tools to manage complexity.

Games are written in C++ because game engines and tooling have person-centuries of work poured into them. Reimplementing Unreal Engine in Rust would require another few person-centuries of work, which is an investment that doesn't really make sense. Economically, dealing with the shortcomings of C++ is much, much cheaper.

But Rust is definitely encroaching in all of these areas. Embedded Rust is doing great, scientific Rust is getting there (check pola.rs). Rust is an obvious candidate for the next big game engine, and it is already quite viable for indie undertakings, though it is still early days.
