I just noticed that even Ben Goertzel, who is apparently totally hooked on the possibility of superhuman intelligence, agrees with me...

... but please bear in mind that the relation of Solomonoff induction and "Universal AI" to real-world general intelligence of any kind is also rather wildly speculative... This stuff is beautiful math, but does it really have anything to do with real-world intelligence? These theories have little to say about human intelligence, and they're not directly useful as foundations for building AGI systems (though, admittedly, a handful of scientists are working on "scaling them down" to make them realistic; so far this only works for very simple toy problems, and it's hard to see how to extend the approach broadly to yield anything near human-level AGI). And it's not clear they will be applicable to future superintelligent minds either, as these minds may be best conceived using radically different concepts.
