obsoletist - A person who thinks new stuff is trash and only uses the old

A person who thinks new stuff is trash and only uses the old stuff because it's the only thing they know.

'I use a typewriter because it doesn't have emojis.'

'I still use a cassette player because I don't know how to use a CD.'

'I use a rotary phone because it's got style and I don't need a phone with a million buttons.'
