My grandpa never got a smart phone. But he was never more than 5 years behind in Home computing well into his 80s.
Gadget nerds have criteria for computers which are not necessarily related to predictability, sturdiness, or fitness for a particular narrow purpose. Instead there is a mix of excitement about technology qua technology, new toys to experiment with, status signaling, etc., in addition to functional improvements for doing real work.
Not everyone shares a gadget nerd’s sensibilities. It’s fine for people to be happy watching TV on a 18" CRT, listening to music on a cassette player, reading paper books instead of a screen, rolling down their car windows with a little crank, playing card games instead of VR games, etc.
