In several different ways.
AI systems can help us analyse the data from complex and uncertain biochemical experiments, and allow us to see new levels and pathways of connection that mediate the age related loss of functionality that our somatic cell lines experience.
Once we understand those, different sorts of AI systems will allow us to model the effects of candidate modifiers of those systems, thus leading to development of effective biochemical technologies for indefinite life extension.
And the third major way is in actually scaling the automation of the technology developed above so that it is deployed to every person on the planet (and thus becomes an individual’s choice as to whether or not they use it).
And of course there are thousands of other subtle ways that different AI systems will assist in the process, in terms of searches, communication through congested networks, visualisation of abstract concepts, manipulation at the nano scale, etc – right out to things like reliable grid energy, reliable food, self driving vehicles making some things viable that were not previously, ….
AI is exponentially impacting all aspects of existence – even to the point of making markets (and economics as most currently conceive it) not simply redundant but actually dangerous in the context of automation and indefinite life extension.
