We've grown up to something technically harder-to-use than an iPad, and I'm comparing today's equivalent.
If we normalize this to current HN audience's childhood (roughly), it's more like not touching a computer and not seeing a modem until 20s, while all the kids know at least how to turn a computer, use Windows Explorer/Mac Finder, developed motor skills to use a keyboard efficiently, know how to modify Word docs etc. and the social norm is knowing all these things (as opposed to our chilhood).
Sure, a legendary hacker might arise after touching a computer first time after 20s, but much less likely.
