I'm not so sure. I think within the HN circle, it seems this way, but I bet if you go ask a randomly selected sample of people, you'll find they use their tech devices to look up sports stats and know better who plays for the Miami Heat than who started Whatsapp, Instragram, Uber, etc. I'm not saying it's good or bad—certainly tech personalities are more visible now than they used to be—but I don't think they've supplanted musicians and athletes in the eye of the general populace.
