Okay look, some of the math I do on a daily basis is like 5 levels above basic addition (it looks like I've written a whole ass sentences of gibberish) but like what if they changed it? I'd rather be sure that 2+2 still equals 4 than be wrong and the thing I'm working on ends up making expensive sounds.
There's also just removing the cognitive load of having to process this information. You're allowed to look up the answer (that's what a calculator and the slide rule do).
Using the tools you have to speed up your work doesn't make you a worse engineer than those in the past. You're building off their work so you don't have to constantly literally reinvent the wheel.
It's actually cheaper to use the USB 3 A ports then it is to use the USB C ports. There's a lot less wiring (and circuitry) that needs to be done for this amount of ports. A full spec USB C port has somewhere between 20-24 pins that are all used if you need USB 3.x speeds. A USB 3 A port has 9 that are used for full data speed. It's orders of magnitude less annoying to run that many traces on a board and keep the data speeds where they need to be.
