There's obviously some nuance here, but the fact is that much modern software is riddled with bugs, and this is sub-optimal for everyone (both software users and software builders). Most of the bugs which frustrate and irritate software users are not due to uncontrollable events such as cosmic rays flipping a bit. Most of them are plain old code defects.
But, you do have a valid point. Allow me to rephrase it this way: The answer is not for software companies to spend unbounded amounts of engineer time chasing every reported bug.
But there are ways that we, as an industry, can do better, and it's not by pouring all our time into chasing hard-to-diagnose bugs. Here are a few ways that I personally see:
1. Some very powerful technologies for finding many bugs with little engineering effort already exist, but are not widely used. As an example, coverage-guided fuzzing is amazingly good at finding all kinds of obscure bugs. The idea of coverage-guided fuzzing was known from the 1990's, but it took AFL (in ~2013) to take it mainstream. Even now, much of the industry is not benefiting from the awesome power of coverage-guided fuzzing. And there are other, equally powerful techniques which have been known for a long time, but are even less accessible to most software developers.
So: spread the word about such techniques, and for programming language/platform developers, work on making them more easily applicable. This could help many software companies to catch a great number of bugs before they ever go to production.
2. Similarly, there are extant historical computing systems which had very powerful debugging facilities, much better than what is currently available to most developers. The ideas on how to make our platforms more debuggable are already out there; it's now a matter of popularizing those ideas and making them readily accessible and applicable.
3. Since it's widely known that many bugs (real bugs, not "cosmic rays") are extremely hard to reproduce, an admirable target for us to aim for as developers is to implement debug logging in a way which allows us to root-cause most obscure bugs just by examining the logs (i.e. no need to search for a reproducer). Some real-world systems have achieved that goal, with very good results.
4. While there is currently much buzz about using LLM-based coding agents to write code, I think an almost better use case for coding agents is in triaging bug reports, diagnosing the bugs, finding reproducers, etc.
I've recently had a couple of shocking experiences where, just given a written description of an intermittent, hard-to-diagnose bug, a coding agent was able to search an entire codebase, identify the exact cause, and write a reproducer test case. (And this after multiple experienced human programmers had looked at the issue but failed to identify the cause.)
In summary, I think there are ways to "cut the Gordian knot" of bug reports.
