Randall Parker lends his voice to common sense foresight for medicine and longevity: "I would [argue] that the general advance in biotechnology, with the continuing development of much more powerful tools to measure and manipulate biological systems at the molecular level, makes the idea of rejuvenation seem much more attainable. ... [we should] expect orders of magnitude more powerful tools in a couple of decades. Just as the shrinking size [of] computer technology allows computer chips, hard drives, fiber optics, and transceivers to go through long series of doublings in capability so does the miniaturized level at which biological instrumentation advances. Why shouldn't we treat aging as curable? The amazing physicist Richard Feynman gave a speech in 1959 entitled There is plenty of room at the bottom where he argued that we can develop the ability to manipulate matter at the molecular level. A continuing trend in technology since that speech has been the development of tools to better measure and manipulate increasingly smaller amounts of material. ... That trend is also going to lead to technology that allows us to make nanodevices that can repair human tissue at the level of individual cells and molecules."
