I feel like long before LLMs, people already didn't care about this.
If anything software quality has been decreasing significantly, even at the "highest level" (see Windows, macOS, etc). Are LLMs going to make it worse? I'm skeptical, because they might actually accelerate shipping bug fixes that (pre-LLMs) would have required more time and management buy-in, only to be met with "yeah don’t bother, look at the usage stats, nobody cares".
