Solomonoff induction is extraordinarily unhelpful, I think... that it is uncomputable is only one reason.

Because it's output is not human-readable being the other?

I mean, even if I've got a TARDIS to use as a halting oracle, an Inductive Turing Machine isn't going to output something I can actually use to make predictions about specific events such as "The black box gives you money under X, Y, and Z circumstances."

Well, the problem I was thinking of is "the universe is not a bit string." And any unbiased representation we can make of the universe as a bit string is going to be extremely large—much too large to do even sane sorts of computation with, never mind Solomonoff.

Maybe that's saying the same thing you did? I'm not sure...

Can you please give us a top level post at some point, be it in Discussion or Main, arguing that "the universe is not a bit string"? I find that very interesting, relevant, and plausible.

Thanks for the encouragement! I have way too many half-completed writing projects, but this does seem an important point.
