I mean, someone from the 70s would definitely be surprised by the specific technologies we have (and don't have). I don't think they'd be surprised to learn that every person has a personal computer (of some type) or that technology has become so ingrained into our culture. It was pretty clear back then that computing and electronics were on a very fast trajectory to more or less where we ended up. I only did a cursory search, but seems like by 1970, IBM was worth nearly a billion dollars. It was a pretty safe bet.
