Wow, thanks! That's AMAZING, it'd be really fun to learn some more about those.
Also, due to this I've updated a LOT towards trusting that class of intuitions more, including all the previous Absurd predictions of it. The world is a LOT more interesting place to be now!

Like my other draft, this is for the special issue on mind uploading in the International Journal of Machine Consciousness. The deadline is Oct 1st, so any comments will have to be quick for me to take them into account.
This one is co-authored with Harri Valpola.
EDIT: Improved paper on the basis of feedback; see this comment for the changelog.
