I mostly agree - however there are physical/mechanical reasons behind the use of some of those. For example, Phillips head screws will ‘cam out’ (driver will slip out of the screw head) rather than get over-torqued, which is useful in various situations - although TIL this was not actually an intentional design feature!

Hex keys are better than a Robertson (square head) in tight spaces with something like an Allan key, and, in my experience anyway, Robertson can take a fair bit of torque, so they’re great for sinking into softwood - and also for getting out again, even when they’ve been painted over.
Flathead screws, on the other hand, should launched into the sun
After having recently restored some stuff from an aging external hdd, i’m seriously considering getting a few dvdr discs and burning the important things every now and then.
I know they don’t last forever either, but - just as a random example that has definitely never happened to me hahaha - you can drop them from a height of 3 feet and still get files off them!
