I certainly think more people are aware of things they wouldn’t have otherwise been aware of. It’s become more difficult for governments to hide facts from their citizens, and that’s been good.
It’s been a mixed bag and I think we should be careful of judging the Internet by the behaviour of companies like Facebook.
We’re also learning. Ten years ago I can’t imagine anyone quitting social media due to concerns about privacy, manipulation, the undermining of democracy or the amoral behaviour of Facebook’s employees, but that happens a lot now. As PG said, it takes time for us to “develop antibodies” to these things.
But secondly there's also the issue of social media mass manipulation, which MAKES (or strongly pushes) people to act like they do. This is completely separate to how "smart" the community is.
