In 10 years the mentality evolves.

It used to be considered extremely rude to pull out your phone during a conversation, now all the under 20 do it.

“evolves” is doing an awful lot of heavy lifting there

20 years ago the world wasn't so tense and deeply polarised as it is now either. I think many people would object more now, not less.

Google glass isn't that old though. It started in 2012 with selected testing users and in 2014 it became possible to just buy one.
