What bothers me most and even on HN, where you usaully get intelligent discourse, the alarmist pessimism. Everything is falling apart! Just another form of self-indulgence. There must be something compelling about pretending the apocolypse is tomorrow.
Yes, there are problems in our social, political, ecomonic systems. They need to be recognized and addressed. Democracy makes that process slow and difficult. But the pessimism to me is one of the biggest dangers.
