One of my high school teachers impressed the same caution upon my cohort but was missing the end of a finger.
The mythology is strong: I am especially amused by youtube woodworkers who, when cutting sheet goods, make "initial" cuts with a tracksaw, because it's so much safer and more practical, and then do "final", "precise" cuts on their table saw. I cut my sheet goods once, with a tracksaw (parallel guides FTW), and they are perfect.
There are masses of people who have never felt the exhilaration of throwing themselves into life and finding that they have built-in tools to deal with it.
I learned to cut 2x4s floating them in on hand with a circular saw in the other, cutting so the longer one side remained in hand without the concern of binding.
It is best to learn from old men with all their fingers or young ones with digits numbering less.
The first time I've seen the argument was in the prag-prog magazine that sadly is not active anymore.
