I'm not affiliated with the site, but I found this interesting. Especially the quite nuanced discussion about if rust is hard or not.
With my background in systems level safety critical hard realtime C++ (plus a bunch of functional programming as a hobby) I feel that the answer was no (for me personally). Basically learn about lifetimes and borrowing and then learn the syntax, done. (Async and unsafe are arguably harder, but again I had the requisite background for it to be mostly familiar, though haven't needed to write much unsafe yet.)
But it was very interesting hearing the other perspective as well! Why rust might feel hard if you have a background in JS/Python/Go etc.
And it was awesome to hear such a nuanced discussion on the Internet, that is truly a rare thing these days.
