there are also no proof that computer didn’t already do that. "to contemplate its own existence" could be independent of a particular level of cognition. (it doesn’t seem to require any complex thinking.)
Consciousness cannot be reduced to computing, to mathematical calculations and such, computers will never contemplate or question anything, unless programmed by a conscious being to do so. Because a computer can't evolve itself, it must be created by a conscious being.
So your modernist-fetishism either ends up in religiousness (Which ends up being correct, this "physicism" or "technologicism" is a religion) or it doesn't "contemplate itself" and remains as mysticism.
Computers aren’t abstract mathematical objects, they are physical objects. Then "consciousness cannot be reduced to computing, to mathematical calculations and such" could be true, but it doesn’t imply computers can’t have consciousness.
The mind-body problem is solved, there is no problem: Dont skip drinking and eating for long, or you will have nomind. Or, consciousness is based on material relations (mechanism s too cognitive), yet those relations are morethan dynamic and complex. Batter ways to counter mechanists than metaphysik
This proof fetishism tastes like burned pumpkin. What proof do you need? We know a great deal about the emergent qualities of mind, and that it can only emerge from a body. Mind is nothing but a capacity of bodies. There are bodies, ideas strolling around, and some obsessed with boring dualities.
