I am leaning towards pessimistic because I think it’s going to take the entire world as a collective to solve the worlds problems (hunger, climate change, etc...), and I don’t think we’re close to having that happen. Though I will say having powerful individuals with a huge sum of money having their lifes mission to solving this problems wiggles the needle a little towards optimistic.
Technologically I can’t see how the world won’t be a distopian future a-la Altered Carbon with technology being used to reduce privacy and credibility.
It just seems like there will always be this cycle of opression, and those with incredibly strong values fighting for our freedom. Ebb and Flow of the human race I suppose.
In the greater scheme of things, money is not the issue. Being optimistic and making a difference on your own patch through smart and focused effort is the start. If every person takes that approach then many large scale problems become a lot smaller.
