The impact that psychedelics have on you is at the level of physical changes to the brain itself, like brain chemistry. Your mind is really really complicated software that runs on the brain. Since brains are universal computers, they can simulate any physical process including any idea. Basically, it doesn’t matter whether your brain is a Mac or a PC because any universal computer can run any software.
The issue with the psychedelics is that there are many levels of abstraction between the hardware level of the brain and high level ideas, like empathy and outlook on life. You would need to be able to explain the causal mechanism of a change in brain chemistry, to the level 1 ideas, to level 2 ideas, and on all the way up to something like level 30 ideas.
ET starts talking about how the brain is like a software project at about 27 minutes into this podcast.
