I'm not sure why a knowledge of computer science would make the UD
astonishing. If anything, I would have thought the opposite. I'm
interested to read your post to Tom and George.

The notion of dovetailing is really the theory behind timesharing, so
simple dovetailing must be pretty obvious, at least since the early
seventies.

That one can dovetail on all possible programs must be pretty obvious
once one realises that these can be enumerated. Of course the
philosophial consequences of being able to do this is not so obvious,
and as far as I know, you are the first person to have thought about that.

Without the philosophical consequences, one would just think "so
what?" So it is perhaps not surprising noone mentioned the UD before you.

I sympathise, but I'm still having trouble getting the connection
too. Nevertheless, I find it intriguing.
