I genuinely don’t know where you’ve gotten the idea that you can “never change your mind” about anything.

I have changed my mind plenty of times about my Rust programs, both in design and implementation. And the language does a damn good job of holding my hand through the process. I have chosen to go through both huge API redesigns and large refactors of internals and had everything “just work”. It’s really nice.

If Rust were like you think it is, you’re right, it wouldn’t be enjoyable to use. Thankfully it is nothing like that.
