I think you may be misunderstanding what GP means. It's about spending a day working on issues. You're either doing it before you launch your iteration, or you're doing it after. GP thinks it's better to spend the time before you push the change. From a quality perspective it's hard to see how anyone could disagree with that, but I can certainly see why there would be different preferences from programmers.

I don't personally mind debugging, too much, but if your goal is to avoid bugs in your running software, then Rust has some serious advantages. We mainly use TypeScript to do things, which isn't really comparable to Rust. But we do use C when we need performance, and we looked into Rust, even did a few PoCs on real world issues, and we sort of ended up in a situation similar to GP. Rust is great though a bit "verbose" to write, but its eco-system is too young to be "boring" enough for us, so we're sticking with C for the time being. But being able to avoid running into crashes by doing the work before your push your code is immensely valuable in fault-intolerant systems. Like, we do financial work with C, it cannot fail. So we're actually still doing a lot of the work up-front, and then we handle it by rigorously testing everything. Because it's mainly used for small performance enhancement, our C programs are small enough to where this isn't an issue, but it would be a nightmare to do with 40.000 lines of C code.
