"With big change comes big resistance". And the bigger the change the harder the resistance will be. Blockchain is just one of many things happening right now, but a very essential one. The world is a big mess as of now, and of course things could go for the worse. I prefer to focus on a positive outcome though (even being a huge pessimist :p). Trust me when I say that if we don't make these changes for the better, that you don't wanna live here 100 years from now...
But yeah, I do believe we can change, I got hope and faith ^.^
