Just be clear, it is not a case of I don’t want to learn anymore. That’s actually pretty far from the case. As an example and sticking to programming languages, I am currently putting Koka and Eff through their paces and learning a decent amount about the incorporation of algebraic effects into languages at scale, I’m also working my way through Idris 2’s adoption of Quantitative Type Theory. I genuinely enjoy learning, and particularly enjoy learning in the comp sci field.

But, that doesn’t have any bearing on my lack of desire to learn Rust. Several other comments basically demand I justify that dislike, and I may reply, but there is nothing wrong with not liking a language for personal or professional use. I have not taken any action to block Rust’s adoption in projects I use nor do I think I would succeed if I did try. I have occasionally bemoaned the inclusion of Rust in projects I use on forums, but even that isn’t taken well (my original comment as an example).

Productivity is incremental. In a couple of hours, you could figure out enough to clone a repository of a project you care about, build it successfully, and make a trivial change (e.g. improve an error message, or add an alias to a command-line argument). That doesn't mean you know enough to start using Rust for your next project.

This is an irrelevant and disingenious hacker jab (oh look, they’re not a “real hacker”).
