I'm not trying to evangelise. I think the argument that Python is a poor choice because it is "too slow" is based on the assumption that speed of execution always matters. Sure, sometimes it absolutely does, but a lot of the time Python is fast enough.
At risk of nebulous repetition: There are many reasons one might choose a particular language. If you or your team find TypeScript or Go more amenable, by all means, use them.
I think "Python is slow" is reductive and frankly just as useful as saying "Python begins with a 'P'". The story is more complicated than simply speed of execution.
Choosing a language is a game of trade-offs: potentially slower execution in return for faster development time, for example. If your team is already familiar with Ruby, will asking them to write a project in Rust necessarily result in a better product? Maybe, but it will almost certainly take much longer.
Anyway, how many Python programs are actually "too slow"? Most of the time, Python is fast enough, even if heavy computation is offloaded to other languages.
As for Rust being the best language of them all, that's, like, your opinion, man.
I think it is important to be reminded that first and foremost they are humans too. A basic level of respect does not mean you like or agree with them. Leading with the statements emphasises that.
Besides, aren't their last words the entire point of the site?
Writing is ultimately just a communication tool. I think the author communicated their ideas effectively. I don't think that it is necessary or appropriate to speculate whether or not they have a learning disability.
