I have a friend in the medical field who doesn’t think ai will ever be able to do any task a human can and then better, so far in trying to construct a reasoning argument that doesn’t go with any assumptions plz help, so far I have:

1. The brain doesn’t seem to do any magic and is entirely made of matter and follows the laws of physics.
2. With enough computational power you can simulate any real world system.
3. The human body is a real world system.
4. Given that, with enough computational power you can simulate the entire human body.
5. Given that, you can simulate a entire human brain organelle with enough computational power. 6.Given that you now have a system in place where you have a computer that can do any mental task a human can do if it’s simulating the entire brain.
6. With enough computational power you can speed up a simulation.
7. If you agree to all this then you now have a computer which can do any task a human can do but faster without doing any magic.

-This isn’t saying that simulating a brain is the way to AGI but it’s just to create a logical proof to show that AGI is possible without creating any new magical tech.
