My current favorite theory about what's gone wrong since the 1970s is that we stopped innovating to maximize performance and started optimizing for energy (and resource) efficiency.
Imagine all the cool shit we're gonna build once we have abundant sources of clean energy...
Takes that aged badly: see this from 1937 the problem with our modern world is all of these newfangled toilets and umbrellas get rid of the books!
do you ever find it weird that as a culture we decided that “progress” just means advancement in technology and numbers on a spreadsheet,
and that things like moral advancement, human joy, positive relationships, fulfillment, psychological development, and purpose don’t count?
