Still some today have no computer experience.
I tutor seniors in how to use computers, (aside: best pupil is in 80s , never used computer , got up to speed within 6 lessons1), I had a 55 years old in transport industry, best driver in company , they wanted him to be 'in charge' but that means a desk job and a computer to use. He tried but did not get on with computers. He eventually learned how to do basic things, then they promoted him. Later found he resigned due to 'no human interaction in job' extreme boredom.
