Why quantitative? I have friends at most major tech companies and I work at a startup now. You shouldn’t write by hand what can be prompted. Doesn’t mean the hard parts shouldn’t be done with the same care as when everything was handwritten, but a lot of minutiae are irrelevant now.
Because anything not quantitative is either “trust me bro” or AI marketing. Some of us are engineers, so we want to see actual numbers and not vibes.
And there are studies on this subject, like the MITRE study that shows that development speed decreases with LLMs while developers think it increases speed.
