The standard pseudo-Kuhnian claim that science needs people to die out in order for new ideas to be accepted isn’t actually supported when one looks at many examples of new theories coming into play. For example, Einstein’s work was accepted by many older physicts who had all their lives worked with Newtonian mechanics. Furthermore, part of the reason some of the older ones don’t adopt new ideas is that they are simply set in their ways and have trouble learning new ideas and methods. If we do a good enough job with preventing the negative aspects of aging, that won’t be an issue since brains will still be flexible.
