There could be something that [locally] rolls back time or creates brances to error correct conciousness.

I'm not arguing that consciousness is and illusion. I'm only arguing that it is possible that it could be an illusion. It's probably not, and if it were, it wouldn't matter. I'm just saying it's possible.

I doubt it makes a difference. If it exists it is real regardless of implementation.

It can only be considered fake if it is a replication of something else and is inferior.
