Life Extension

In Response to Trevor Lowman – Facebook – Life extension – “Do you believe that it will ever be technologically possible to rejuvenate a human being”…

[ 2/1/21 ]

Just because we give a singular name to things like “cancer” and “aging” does not mean that they are singular things.

Aging, the gradual changes and loss of function that we see with age, are the result of many different sorts of processes.

Perhaps the single greatest of these is the antagonistic pleiotropy that exists between the anti cancer properties of telomere length and the limitation on the number of cell divisions they impose on any line of pluripotent stem cells. In order to remove that restriction on cell divisions, we need other effective mechanisms to limit cancer.

And as mentioned above, cancer is not a singular thing.

A reasonable definition of cancer is anything that inhibits any of the many levels or types of cell to cell communication that prevents individual cells from replicating beyond the need of the cooperative that is us. (Note – same sort of thing {limits on human reproduction} is required at the societal level, if we as a social species are to survive, or any of us as potentially long lived individuals within a social system are to have a reasonable probability of living a very long time with reasonable degrees of freedom.)

So developing mitigation measures to all the many classes of issues that cause loss of function with age is going to take some very high tech innovation. Some of that will involve nanotech systems within our bodies, some will involve genetic modification at the cellular level, and some will involve ongoing maintenance systems.

Developing that technology is going to be very complex in the first instance, and then the entire process of manufacturing and deploying it needs to be fully automated, and that involves many levels of profound change and profound security issues.

So I see it as entirely possible, and I think it probable that major advances towards it have already happened, but the technology is not yet at the stage that its production and deployment can be fully automated, and therefore made available to all who want it, and it is therefore being kept very secret.

And on my reading of current trends, I would expect to see this technology being generally available in the 2030s, though there are likely to be significant issues discovered with it for the following 50 or so years, requiring significant system modifications as we go on, and for the most part they should be survivable by the individuals encountering them, if done well.

Seems like I might be a cancer survivor. Thinking about the systemic incentives within the world we find ourselves in, and how we might adjust them to provide an environment that supports everyone (no exceptions) - see
