I love reading about self-driving cars and cryptocurrencies on HN. Suddenly, all the orders-of-magnitude improvements in efficiency/performance/scaling/production/integrity/etc. go out the window. Apparently they get replaced with conversations that devolve into how bad humans have been at the tasks that the fanboys are hoping get replaced by marginal-at-best tech. E.g., git discussion on HN: of course we all know how git leverages merkel trees to make it workable to produce millions-of-line ambitious projects across timezones with people we've never even met before (much less are willing to fool around giving repo permissions to). But goddammit it takes more than five minutes to learn the feature branch flow. That's unacceptable! self-driving car discussion on HN: I've seen plenty of human psychopaths nearly mow down a pedestrian at an intersection so how is software doing the same thing any worse?
