So much have changed. The way we shop, travel, navigate a town, the way we socialize, receive information. My formative memory is during the transition from computers are a furniture piece and internet a thing you do to being on your pocket with constant high speed connection and the difference is incredible.
I was also part of the people that thought everyone having access would turn out a lot better than it ended up being. I think the issue is not that it did not change much, is that good changes got offset a bit by a lot of very bad outcomes.
No comment on the distribution and concentration part, that one I agree.
