I can do the same thing with rust, but making changes to that monstrosity would be relatively hard. With Python I can rip something out and replace it without a whole lot of fuss. After doing that for a few days or weeks, I might know what I should actually build.

At this point, building with rust is pretty quick but it’s only because I’ve got a clear target and a somewhat sensible design to follow, if I squint at it. Then I can drop kick the Python part and pretend it never happened.

But I’ve never worked with anyone who works at the same speed in Rust from the start. It doesn’t seem to happen. On the other hand, I’ve watched people struggle with it for days and weeks on end over things that seem trivial.
