The speaker discusses the concept of living in a simulated universe, based on a modified version of the original simulation argument by Nick Bostrom. The speaker outlines five assumptions:
1. It's possible to simulate consciousness.
2. Technological progress will not stop anytime soon.
3. Advanced civilizations don't destroy themselves.
4. Super advanced civilizations want to run simulations.
5. If there are a lot of simulations, you are probably inside a simulation.
The speaker argues that if these assumptions are true, then the chances are not zero that you are living inside a simulation. The speaker suggests that the majority of all conscious beings that will ever exist are simulated. However, the speaker emphasizes that all this is based on a lot of assumptions that we can't really test right now. The speaker concludes by encouraging viewers to try to live good lives and have a good time, hoping that if they are simulations in a supercomputer, nobody trips over the power cable.
1. Humans are unable to experience the true nature of the universe unfiltered, as our senses and brains can only process a fraction of the world.
2. Technological progress has widened our knowledge about the universe and made us aware of unsettling possibilities in the future.
3. There might be a possibility to simulate entire universes, but it's uncertain whether this has already happened.
4. The current understanding of physics suggests that it's impossible to simulate the whole universe with its trillions and trillions of things.
5. We only need enough universe to fool the inhabitants of our simulation into thinking that they're real.
6. If our current understanding of physics is correct, then it's impossible to simulate the whole universe with its trillions and trillions of things.
7. The brain runs at about 10 to the power of 17 for 100 million billion operations per second.
8. We want to simulate all of human history at once so we can skip around.
9. We want to simulate 200 billion humans with an average lifespan of 50 years.
10. One year has 30 million seconds times 50 years times 200 billion humans times 10 to the power of 20 operations.
11. A computer able to handle a million trillion trillion trillion operations per second is required.
12. The number of operations required to simulate human consciousness is 10 to the power of 20 operations.
13. Technological progress will not stop anytime soon if it continues in a similar fashion as it has so far.
14. There might be galaxy-spanning civilizations with unlimited computer power at some point.
15. These beings might be so advanced that we could barely distinguish them from God's.
16. Advanced civilizations don't destroy themselves.
17. We see no alien civilizations in space, which might be due to great filters.
18. When we speak of posthuman civilizations, we don't know what we're dealing with.
19. Super advanced civilizations might want to run simulations for whatever reasons and assumptions.
20. If there are a lot of simulations, you are probably inside a simulation.
21. If there are simulated civilizations, it's likely that there are a lot of them.
22. After all, we assume that posthuman beings have access to practically unlimited computing power.
23. If there are billions of simulated universes, there are probably trillions and trillions of them.
24. The chances of you being one of the simulated ones are pretty high.
