alt Hacker News> People tried to "just do that" (write their programs in a memory safe way) in C and other languages with manual memory management for decades, and we have countless vulnerabilities that prove this simply doesn't work.
Who are these "people" you speak of? It's possible to write software in low level languages that don't have these problems. Not a "non-zero" it might be possible, it can be done thoughtfully, and the popular notion it can't be done is backed only by incomplete anecdotes.
Should everything be written in low-level languages? No, that would be absurd. Is it a simple fact of life that not every person/team/organisation is capable of meeting certain standards of rigour? Yes. That's not to say anyone in the Bun team could not become sufficiently competent in the future. For whatever reason, current experience, incentives, and personal motivations did not make for a conducive environment to make Bun watertight in Zig.

Just people like the linux kernel, all major browsers, most of our popular webservers, etc and basically all non-trivial software projects written in C.
The good news here is that we have more than just anecdotes to support this, we have empirical evidence.
Yes, it's possible. It's also possible for experienced pilots to fly an airliner completely manually for the full duration of a transatlantic flight without crashing. Still, over the last decades, autopilots and other assistance systems with ever more sophisticated features have been developed, and I would argue that without this technology crashes would be much more frequent than they are today. Same goes for memory management: you can do it manually, and it might work out most of the time, but if the programming language is helping you with it, the likelihood of memory safety issues decreases drastically. And the problem with avoiding these issues only by "meeting certain standards of rigour" is that you might only find out that you have failed to meet them years later, when you learn that your software has a vulnerability.
