Nobody said anything about people born in the 70's. They said "musicians who didn’t want to learn technology in the 70's", which is clearly different.
Those musicians were probably 30+ in the 70's, making them 83+ now. Life expectancy of someone who reaches 30 is 48 years, so yes: most of them are dead now.
