Old =/= not tech savvy, and young =/= tech savvy. I'm sixty five and regularly explain how to use computer/tech gear to the 20 and 30 year olds I know. Don't assume that the generation that invented the modern personal computer and the Internet doesn't understand smart phones.
Considering today's tech is way easier to use than the one in the 1980s and 1990s, I always find it very funny that anyone think the kids these days are tech savvy. Have you really talked to them about how those devices they're using work? Do they know anything about how they work?
NOT A CHANCE.
Someone who has had a personal computer since 1987 like my mother (Born 1947), knows a lot more about computers and tech than them. She's now used Windows all versions from 3.0 to 8.1 AT HOME, plus had to deal with dos 3.3 and 4.0 and all those ugly memory managers and network stacks! She started using a PC in 1987 (at 40). She doesn't have a tech degree, she basically graduated high school in the 1965 and that'S it; but she could run around those young guns on just about anything tech.
