I wish ad tech wasn't a thing, I wish we hadn't produced so many winner takes all monopolies. I wish the early promise of the web had been more fully realised I guess. I think the kind of idea Tim Berners Lee is promulgating with Solid is the kind of the thing I'd like to see take off. Who knows if the horse has bolted, I guess we shall see....
Im not depressed about it as such, I work in tech and I try to fight the good fight and work on projects I believe will actually help society. I also remind myself that no ideal is ever reachable and everything ends up reflecting its situation ie the Web reflects all aspects of human nature and also the socio economic system of the cultures it is embedded in. Like in politics, we can't realise ultimate ideals but we can muster all our strength to make incremental progress towards them.
