The other thinks slowly, often has no initial opinion, and rarely speaks up, but when they do, the input is flawless and monumental. R&D is their forté.
Neither one is better than the other. The quick thinker handles in-the-moment action well, but is so wrapped up in the “now” that it’s difficult for them to get too deep on a topic. The slow thinker meditates on ideas for a while, carefully chooses (almost always the correct) path, and steadies the course. Prick and pull at this one for a quick thought, and it comes out flatter than you could imagine.
Until we know what actual intelligence is, trying to act like one form is objectively better than another is just silly.
I think lots of the graybeard devs are deep thinkers, not fast thinkers. I think fast thinkers were pulled towards the “move fast and break things”-style companies.
