I’ve seen the “outside” world. Our world, the Earth, is synthetic. The universe is embedded into a much grander and complicated larger world. The larger world is absolutely teaming with life with a diversity you would have a difficult time believing. Aliens, and so forth, are much more advanced than anything you can easily imagine. There’s also a lot of hostility out there.
The Earth is more like a closed circuit shared holographic network experience, rather than a physical place. Real AI is very much a thing. What we see on Earth is like fractal recursive mirroring of the real world. Human beings are a product of social engineering. And, the Earth is more like a virtual house in which all other kinds of beings call home. If you increase your awareness, you can actually learn to communicate with these other beings.
