Think about it. The more you learned about your brain the more complex it would become. Also I’m not sure we have enough capacity to reflect on ourselves by processing everything. Think about the massive complexity of every connection. Could someone actually process that or are we limited by ourselves?
Depends what you mean. If I’m understanding you, then no, you’d be dealing with some kind of metadata recursion problem. On the other hand, on my hard drive I have a file detailing the schematic of the drive.
