Science isn't failing us. Big bureaucracies getting in the way of science are failing us. Even just to experiment with semi-controlled drugs, for example, is a massive headache and ungodly expensive. Everybody wants to get into journals and paid by government institutes, so a lot of science being done is very safe and not venturing out to the controversial as much. Studies are being funded by corporations looking to get some cooked data to support their bullshit.

Science has never failed us, as science is inherently just human curiosity. The continuing structural growth and big bureaucratic developments that many governments, schools, and businesses are implementing are failing us.

"Bureaucracy is the art of making the possible impossible." - Javier Pascual

Science can't fail. It only illuminates. But a lot of shady assholes run this place, and the last thing they want is a light shone on them.
