Whaddya mean you technical guys only understand hex?!? I spent plenty of time dealing with binary too. I guess because half my career was hardware design.
Maybe it's just you software only guys who think in hex.
I was half kidding but it is true that we don't use binary much in programming, we do use hex in instance where the cursor needs to advance to the next line for example, would would embbeded hex characters 0D and 15 at the end of the line.
