Most people who use computers don't know what a "chip" is. If you are
capable of identifying an integrated circuit from its part number, you
are a veritable electronics guru compared to 5.9999999 billion people.

Remarkable. Not heard that one before.

OTOH, I have set up many a serial printer. RS232 was a complete pain
in the **** and I am very glad to see it die. Start bits, stop bits,
word length, parity, baud rate - hateful. Apple could do it right in
1984; there was no good reason for everyone else in the industry to
screw it up.
