This is an interesting idea:
In my book You Are Not a Gadget, I did an experiment. Whenever I was around people and there was music playing, I asked them if they could tell me in which decade the music they were listening to was made. I was quite taken aback by how people can’t tell this decade from the previous one, whereas all the other decades seemed very distinct to them, including very young people. It is as if some kind of cultural stasis has happened, but it’s hard to say whether that is down to the Internet.
From here.
As we reduce the discovery cost of finding people, services, and even our personal preferences, surely, the benefits of the discovery process start to disappear.
