alt Hacker NewsI still don't know what you're getting at. I think you're either positing that there is some yet undiscovered force or particle in physics that gives rise to consciousness (e.g. some kind of soul particle), or you think the particles within our current understanding of physics are sufficient, in which case consciousness could be built.
Obviously consciousness can be built. I'm getting at the obvious point that physical processes depend on specific arrangements of materials. I can build a computer in an infinite number of ways. Here's one: Write the full machine state on a big sheet of paper in pencil. When you're done, write the next one (this will take a while). The machine you're simulating is running an all powerful "AGI". It is preposterous to believe this is conscious though.
The simpler belief than the idea that just any intelligent process is conscious is that consciousness is some kind of physical process that happens in particular conditions.
