t’s a valid point that we would have to make some improvements to the human brain in order for longer lifespans to be enjoyable. Neuroplasticity decreases as we get older, and advanced age can bring Alzheimer’s, dementia, and other such disorders.
I can’t really see this as a problem at all; it’s always seemed to me like an erroneous assumption that whatever technology allows the human body to stay healthy indefinitely will work on the rest of the body but not the brain.
Neurogenesis is not trivially similar to cell division in bodily tissues, so a technology which assists the latter may not assist the former. I think it is likely that some combination of methods will be required.
