“I think, in general, medicine in the 21st century will switch from healing the sick to upgrading the healthy... If you find ways to repair the memory damaged by Alzheimer's disease or dementia and so forth, it is very likely that the same methods could be used to upgrade the memory of completely healthy people.”
