You are comparing code to a tshirt but it is more similar to infrastructure like roads/bridges/buildings. It is like a platform that you build other stuff on top of

I understand what that is but I just don’t care. I am guessing the vast majority of people using rust also don’t care. Justifying the decision to create this mess by saying it is for embedded makes no sense to me.

Also don’t understand why you would use rust for embedded instead of c

"Tight control over memory use" sounds wrong considering every single allocation in rust is done through the global allocator. And pretty much everything in rust async is put into an Arc.

I don't understand what kind of use case they were optimizing for when they designed this system. Don't think they were optimizing only for embedded or similar applications where they don't use a runtime at all.

Using stackfull coroutines, having a trait in std for runtimes and passing that trait around into async functions would be much better in my opinion instead of having the compiler transform entire functions and having more and more and more complexity layered on top of it solve the complexities that this decision created.
