To tack onto this point, I actually had a couple of issues where subtle memory management bugs led to slightly incorrect (not terribly incorrect) results when I was working on a graphics paper. The worst part about that was it wasn't immediately obvious that there even was an error, until much later when we realized that the results we were getting weren't consistent with what we expected.

Something glaring would be if we were getting values that were zeroed out or something like that, but when the only difference is that a slope is -1.4 instead of -1.6 or something like that, you don't immediately realize something's up.

Once we realized there was a bug, it took a long time to track down, and after that I was so frustrated I started writing a new library from scratch in Rust for our research and it worked out pretty well.

Anecdotal evidence for sure but it was really nice not having to triple check for memory race issues.
