Almost all of professional software should be intentionally suboptimal.

This is what we mean when we say that premature optimisation is the root of all evil.

We ought to ban people saying that quote, due to the way it has been abused to avoid considering performance _at all_.

“Intentionally suboptimal” is also a strange way of phrasing it, as it makes it sound a bit like you’re intentionally building something bad, as opposed to “only as good as it needs to be”.
