  1. 7:20 I think one possible simulation argument could be that "The fraction of all posthuman civilizations running whole universe simulations is very close to zero". If future posthuman civilizations run simulations of evolutionary history, they might simulate one human mind at a time and simply generate all sensory information on the fly. This seems like a logical software optimization because the information you could extract from the brain behavior of ancestors should be possible to figure out by simulating just one brain and change what kind of information you allow it to have (that is, change the existing memories and sensory feedback). This would require only simulating full chemistry of one brain and then change the inputs it can receive during the simulation. Humans have very poor I/O bandwidth so it should be easy to simulate all possible inputs for a single human. And since you can fake the experienced time inside the simulation, you could pause the simulation when it's about to go out of known domain and use some superhuman processing to calculate sensory feedback that the simulated human should experience for that situation. That would easily explain why we cannot create any physics experiment to show that we're inside a simulation – any idea we have, the entity running the simulation could just decide to output the results that appear to demonstrate real universe to the simulated mind. And since it's probably only a selected historicians who would be running this kind of simulations, the resulting humans in simulation would be close to zero relative to the history of humans. (It seems that this was later discussed around 25:25.)

  2. 58:00 If you could "push a button" to make you feel like you've just eaten the best meal of your life and you're loved by all persons that are meaningful for you, would you use it? Human brain seems to be really eager to set a new baseline so even when your needs were fully fullfilled this way, it would appear boring really fast. Would we have to press "make me hurt" button every now and then to calibrate our brains?
