@f00fc7c8 Tech optimism in the 2020s is fueled by a revolutionary new philosophy of ethics called "Effective Altruism", or "Longtermism". The premise of "longtermism" is that you ignore short-term concerns like "how do we feed the world today?" and also "medium"-term concerns (50-10,000 years from now) like "are our cryptocurrencies destroying the environment for the next seven generations?" and focus on what matters: The wellbeing of entirely hypothetical boltzmann brains 10^100 years from now
