3. the Gauss–Jordan elimination argument is *really* flaky. GJ is just an extremely poor algorithm in general, and should not be used at all, but replacing the epsilon check with a 0 check doesn't really help in its application. “Very imprecise” can be quite catastrophic depending on applications.

@lisyarus@mastodon.gamedev.place 4. the user input case really brings out the fact that main pain point with epsilons isn't even the epsilons themselves, but the fact that they are chosen *arbitrarily*; however, this is a very different matter compared to “don't use them when they aren't needed”. (yes this connects to point 1. above) THE END.
