The problem is is that superintelligence has been re-defined. Under current models it aint gonna happen no matter how sexy the presentation and thoughts inputted. Eating potatoes or whatever doesn't make you smarter. Take all the German scientists back end of 19th-20th century. Stodgy European food. And it worked. They delivered. Now Asians have much better cuisine but they are now catching up and may yet end up as the best is yet to come. Drugs are good. Esp Opium. Cognitive enhancement big time. Yet again those cultures that enjoyed it staid within their cultural milieu for ages. Again things have changed but that option should be made available to all everywhere. The rest is gimmicky. Interesting in itself as itself. Take whole brain emulation. I mean that is what babies are. Re-creating brains and or designing wetware is silly. Plus the brain so emulated may have ideas of its own and turn DALEK on us. The essence of intelligence is resonant sentience. Meditation techniques esp Ch'an-Zen [and related] Buddhist practices will give results but this takes years and even then no guarantee. But this self enhancement seems more logical than a lot of machines thinking they think by merely puzzling out solutions that are in essence given anyway. The Mind. That is the centre of everything. Molecular enhancement will for now be the best bet.
