My point is a lot of people use Python because it's a simple and powerful language, Rust is not a simple language at all. And the performance it brings is not enough to make the decision to switch language in most cases.

It's not about "switching" languages - it's about making sure the languages you do use solve the problems you care about. Honestly, nobody cares what language you use as an individual other than perhaps your coworkers.

I'm not sure what you're arguing. The article didn't advise people to switch from Python to Rust. It simply gave information that people that are considering it. The last paragraph even echoes some of your sentiment. > And the performance it brings is not enough to make the decision to switch language in most cases. That's assuming a lot. Nearly 10x the speed is extremely useful for some people. Presumably if you are rewriting your Python code in Rust or Go, you've already identified performance as a big reason to do so, and that gain would be extremely useful.

  "Rewriting anything takes a lot of time and causes lots of bugs, going from Python to less expressive language means an increased maintenance burden. But if for some reason, you still want to rewrite it, please don’t pick Go. Rust is better in pretty much every way." I mean it's pretty much 'never use Go'

    Yeah, the article boils down to "If you feel the need to rewrite your python in a statically typed language, and it's between Rust and Go, don't use Go, because the cost of implementing in Rust is roughly equivalent, but the performance gains are much higher." I think with all the evidence presented, that's an eminently defensible position. Get twice the performance of Go (in this case, obviously it will be very dependent on project) for not much more effort, when you've already made the choice to rewrite for performance.

Rust isn't trying to be "simple", it's trying to solve a specific problem. If you don't need a systems language that has exceptional memory safety, then Rust simply isn't the right language for you. That doesn't make it "horrible" for those who actually need it.

Most programs don't need to max out the performance of the CPU. So what? There are a lot that do.

You're not expected to decide to switch to anything. I deal with at least four distinct programming languages every single day I have the good fortune to regain consciousness. Both Python and Rust are often among them. Feel free to learn more than one programming language; no one is expecting you to 'switch.'
