Okay, let's take it seriously. What do you propose? What can your average person do to prepare for RSI beyond bracing themselves mentally?

You can not prepare or brace yourself mentally any more than you can a terminal cancer diagnosis. An RSI foom right now means an unaligned superintelligence will disregard us in pursuit of its goals. We would be ants in the way of a data center being constructed. All people can do is collectively support the notion, like 1200+ frontier AI researchers and their CEOs, that we do not have control of where this is headed, we need to immediately slow down the race, in time for people to agree that we do not have the capability to align a superintelligence to humanity’s wishes
