I disagree with everything you said but I use to think along the same lines. Then one day, in a conversation about collective stupidity someone shared this observation:
There are countless species in this world and all of them are doing just fine without the giant brain. A large part of humanity really just wants to live their live, reproduce, enjoy a meal, sleep properly, sit in the grass and look at the lake and the forest.
We keep arguing that we have to think our way out of whatever the current situation is but you cant find a single problem that was not created by similar "solutions" for the previous "problem".
It sort of blew my mind!
It took a very large brained human to come up with the bread and circuses. It takes such very large brain to punish innovation or to have people ignore it. It takes an even larger brain to argue "what is desperately needed". You talk of saving the world but the world doesn't need to be saved. People are going to die sooner or later regardless. If you or me get to live a little bit longer that would be fantastic for you or for me.... but for the world? The world needs me for what exactly? We are the parasite devouring the host.
I do get it! It seems terrible this "amusing yourselves to death" but why not amuse yourself until you die? Utopia is a world full of 300 year old grumpy old men? I'm sure we will get there eventually if we push hard enough but that will simply become the new problem that those few bright men with their large brains so desperately need to solve for us.
I look at my cat sleeping on the sofa, why doesn't she get to have this complicated disposition? Why isn't she worried about the economy and innovation? What a joke, after the great collapse she will just go fishing, catch birds, spiders and mice, fight the neigbours, roll in the grass, look at the lake and the trees. At least, assuming we leave any of that behind.
Think about it!
The moon? mars? why not go to Antartica if you feel we ran out of self-made problems to solve? Antartica seems just as much umpf as Mars?
