Thank you, good point... not sure. Interestingly, whenever subconscious problem solving is successful, the solution does suddenly jump into consciousness (eg shower thoughts etc). So maybe it's something about the correction part of error correction...

Lately I have wondered if one is aware/conscious of wherever one is trying to detect errors. I learn to ride a bike: very conscious of it, I make mistakes all the time. Then gradually as I iron out the mistakes I grow less conscious of it...

It can't be analog btw because error correction can only happen in digital systems.

And again, a single Turing machine can simulate multiple Turing machines, so parallelism is incidental at most.

I don’t think the presence of understanding (ie knowledge) is indicative of consciousness.

It’s trivial to write a function that represents understanding of a prime number.

I guess that consciousness is related to error correction.
