That's a fair point, but it's also true that we're never going to break away from legacy systems until we start writing software that has a chance of functioning correctly when running out of resources. The good news is that we do have ecosystems where you don't have overcommit, like webassembly and embedded devices, and if you're writing libraries meant to also work on those platforms, then you will have some good building blocks that can be used to iterate towards more robust software. That's how you're expected to approach library writing in Zig.
