And during much of that X-year period the person is very probably going to be retired and drawing a Social Security or equivalent payment. In this case, it’s a net absolutely massive *rise* in costs.
That’s assuming the life extension effect doesn’t kick in until the person is already quite old. That probably is not the case, or the life extension mechanism is not likely to be effective at its goal of extending life. It won’t stretch out puberty, either (probably), so that leaves an effect on early and particularly middle adulthood, which are prime earning years.
If you can extend the amount of time that someone is effectively 40 by about a decade, or even just five years, then sure it isn’t as fun as being in one’s 20s, but it still adds plenty of earning potential.
(Also, trust me, the procedure will be expensive. Look at immunotherapy and biologic cancer drugs and get back to me.)
At first, sure. And the willingness of wealthy tech executives to pay almost any cost for it will fund a lot of the research necessary to make it cheap enough to be more widely available. But while we are on the side of the medical cost curve where medical costs come down from infinity, and therefore costs go up since we start actually paying them rather than dying, there should be a far side of the curve where the costs start going back down again.
We’re growing new organs on laboratory animals, printing new (and functional) organs with 3D printers, and we just got CRISPR. Apparently this year the NHS will be testing some kind of gene therapy on a subset of blind patients. Surgical robots, while not autonomous, are becoming more common. (That’s leaving aside the prosthetic robot arms since those aren’t relevant to aging right now.) Even those immunotherapy drugs are a step up.
On the far side of that curve, the sorts of chronic conditions that cost us so much money are prevented through gene therapy and selective IVF, while tissue engineering replaces organs damaged by disease with natural ones that require no immunosuppressant drugs. Robots decrease the cost of surgery, either by automating part of it or allowing more labor to enter the field from elsewhere in the economy. Critically damaged limbs can be replaced by nervous-system-linked prosthetics (which already exist) produced by highly-automated factories and custom-fit to the patient (factories are getting massive reductions in staff even in places like China), without drastically impacting patient mobility.
Much of the cost is in the research. One can gene mod bacteria to synthesize the desired chemicals, build big heavily-automated factories, that sort of thing.
Many very expensive drugs cater to an illness that is not common in the population. However, the market for life extension is probably at least one quarter of the population in all developed nations, if not much more, and they would be willing to pay an enormous amount of money to have it. That’s a very large number of people to amortize the research cost over.
Now, reading all this, you might say I’m being naive and that it will require personalized interventions for each person, not a nice mass-manufactured one-size-fits-all solution.
But that’s what we have computers and big data for. The market is enormous, and computer power is still increasing, so even if the genes have to be tailored to each specific person, the genetic tailoring can still probably be done by machines.
Now, it’s possible that I’m wrong about this, and it will remain unreachably expensive forever. However, I think that sort of pessimism on this matter is driven in large part by how unattainable life extension has been for humanity, and all the Deathist myths in our culture that tell us that old age and mortality are really better for us, and that the immortality we crave but cannot have would be terrible. In our myths, it is often associated with vampires and other undead, the temptation that drives sorcerers and other villains to do evil and corrupts their hearts.
In fact, weren’t people joking about Peter Thiel wanting to look into the qualities of young blood? But we can just grow cell cultures, and if it’s something that’s common to all young blood, then that sort of thing would only last for about ten years before they crack the secret of how to do semi-artificially it on an industrial scale.
It seems likely to me that either the rich will have life extension treatment and it will become cheaper over a couple of decades, or that no one will have effective life extension treatment worth more than a few years, and not a stable in-between state where we go for a century with only the wealthy having life extension.
