We’ve been here a lot before.
For me, I can imagine living a very long time – millions of years. I’ve been able to do that since 1974.
The logic is clear, all life alive today seems very probably to be part of a continuum of cellular life some 4 billion years old. So indefinite life is the cellular default – it is what our germ line cells do. It is only the somatic cell lines of complex animals like ourselves that show age related loss of functionality.
Given the exponential growth of knowledge, we need to live on, or we will reach a ceiling of human wisdom able to be integrated over a human lifespan.
To me life extension is required for all sorts of reasons.
Social survival – we actually need to have a reasonable chance to live with the long term consequences of our choices to give us personal incentive to make those choices wisely.
It seems logically clear that the machinery for indefinite life exists in our cell line. I expect Calico to find it quite quickly.
Then we get to other risks.
For the large low frequency risks, we need serious engineering capacity in orbit (enough food reserves for 12 billion for 5 years delivery to earth without return). Another Toba event would take us out right now – we’d be down to a population of a few tens of thousands in underground nuclear facilities, not enough to maintain technology. We need to get replicating machines in orbit asap.
We need life extension for everyone, asap.
We need to remove money as a major factor in political decisions, and require all decision makers at all levels to consider the reasonably foreseeable consequences of their actions, and to mitigate the risk to the life or liberty of anyone and everyone – asap.
All of this is achievable, and it will never be the natural outcome of anything remotely resembling a free market system.
The experience of being human could be one of choice and empowerment for everyone.
For most people it is a very long way from that – though most have little conception just how far.
Full automation of means of production
Life and liberty as highest governance priorities.
Sticking all the elements together in a way that actually gives us a reasonable probability of achieving that seems to be the real trick!!!
