I spend some time going through what programmers wrote over the past years and many of them were rewarded for getting things done quickly with no complaints.. The more diligent ones probably didn't last since they got things done correctly which takes a lot more time and thought.

It's why I said quickly and correctly. I think it's a cop out to say someone was slow because they were building it correctly. Famously, the old space shuttle software was developed very slowly because it had to be 100% correct at all times. Most software does not need that level of correctness. Part of a SE's job is to understand that.

I pay a lot of attention when someone claims to have solved a problem I suspect to be NP-hard. There are a lot of possible explanations, for example they may have an incorrect measurement function or they may have chosen a simpler related problem that isn't really NP-hard, or both.

Fast, quality, cheap.

Pick two.

You don't have to pick two exclusively. They are all connected sliding scales. Part of engineering is figuring out where the slides need to be.

Plenty of things are made fast, at high quality, and cheaply.

Some things just aren't very hard to make.
