Yes but you grew up typing hex codes into a home computer connected to a tape drive. You know what 8192 looks like in binary but everything beyond 65535 you struggle with because you didn't have the registers for that on your 6502A.

It probably irritates you to see images scaled to 1000 pixels rather than 1024. What about that jpeg cell that is not 8 pixels square? Think of the computational overhead and the need to go floating point just because someone does not think in bytes. It is too late to tell them now, these kids ain't spending winter typing in hex. Hex to them is like BCD is to you and who needs binary coded decimal these days when emoji's need to be mastered?

I don't mean you personally, just them folk that know their hex from learning to code that way. I think hex is important but it seems most front end developers would prefer not to know.
