Oh wow, The creator in the "flesh"! Thanks for replying to me.
Hypothetical scenario: Let's say you're writing an experimental tool that doesn't exist anywhere else. You don't care about security, you don't care about speed. You just want it to exist so you can see what it does and possibly iterate on the idea if it ends up working out. Would Rust still be feasible?
From my impression of it, you would need to take care of a lot of corner cases and such (which don't exist in other languages) that may slow you down in the short run. I'd imagine those corner cases would be extremely helpful in the long run if you want to squeeze some extra performance out of it (or avoid technical debt). But from the perspective of "figuring out what's possible" I feel like Rust would get in the way a lot.
Good question! The inherent problem with asking me that is that I've been writing Rust continuously for over 2.5 years by now. I live and breathe it. It comes as naturally to me as Go or Python does at this point (which I've been writing continuously for even longer).
I will say that a comparison between Rust and C is much easier, because in the past, I've spent so much time debugging runtime errors in C with valgrind. Rust is an easy win there for me personally. I've never done much C++ so I can't provide a comparison point there.
After a bit of Rust coding you get quite familiar with the workings of the borrow checker, and it becomes pretty natural to work with it. There are plenty of things you can do in C that Rust's borrow checker will forbid because it isn't smart enough to prove it safe, but there are usually straight-forward work-arounds. Sometimes the borrow checker might even help make the code a bit clearer. :-) Some of this is institutional knowledge though, so there's still a lot more documentation work left to be done!
To bring this back to earth: Rust won't replace those ~100 line Python scripts that I sometimes write for quick data munging.
The other important bit of context is that before I started with Rust, I had already had quite a bit of experience with C, Standard ML and Haskell. This meant that the only truly new thing I had to cope with in Rust was the borrow checker, so it might have been easier for me to digest everything than it might have been for most.
