Superintelligence is an incoherent concept. Intelligence explosion isn't possible.
How smart does a mind have to be to qualify as a "superintelligence"? It's pretty clear that intelligence can go a lot higher than current levels.
What do you predict would happen if we uploaded Von Neumann's brain onto an extremely fast, planet-sized supercomputer? What do you predict would happen if we selectively bred humans for intelligence for a couple million years? "Impractical" would be understandable, but I don't see how you can believe superintelligence is "incoherent".
As for "Intelligence explosion isn't possible", that's a lot more reasonable, e.g. see the entire AI foom debate.
