Very much agreed. It's not like the anti-Rust comments are much better. They're often quite biased in the other direction and rest upon arguments that boil down to "if you write C++ correctly, it's a very good language". But of course, Rust has flaws and design decisions that make it a poor fit for many people/usecases. Really I'd love it if people kept an open mind, did their research and tried to not let their biases rule their judgement.
All those arguments, as usual, also fail to discuss the existing ecosystems.
Sure one can somehow write Rust-CUDA but is going to have an uphill fight versus someone just crusing along focused on the actual problem, instead of building infrastructure.
