While this is generally true, I think it’s less true for embedded systems. All of the tools I use at work for embedded systems engineering (JLink, serial adapter, oscilloscope, logic analyzer, nearly all MCU dev boards and FPGAs) are USB-A. I use a MBP and simply could do any work whatsoever without a USB hub. I think it’s fair to assume anyone in the industry can use USB-A.
In the industry, yes, I agree. Except for maybe managers but even they probably have a dock on their desk that includes USB-A.
Edit: I remember something, having done work related to embedded stuff. About 6 years ago, we still had 3.5" floppy drives in a couple of scopes in the lab. We replaced those with a device that internally had the interface of a 3.5" floppy drive, but on the outer faceplate it had a USB-A connector for thumb drives.
I would assume someone doing embedded work would not only have to have USB, but serial. Is that incorrect? It seemed like that was even included in your list?
I usually have two or three USB to serial converters plugged into my computer at work at any time. I expect most embedded people would do similar (or use serial console servers over a network).
