My wife and I started talking about this after she had to help an old lady at the DMV figure out how to use her iPhone to scan a QR code. We’re in our early 40s.
It really depends on the kind of work you do. My mindset is, if you’re interested in it, invest time in learning about it. If not, then not. We don’t have to go all “kids these days…” or look down on people who aren’t as interested in techology as we are.
