I think immortality would be bad for humanity, but ~40 more productive years would be beneficial. Currently we take 25 years of preparation in order to work 35.
I can go into a longer diatribe here, but the short story is:
1) Most people have a hard time finding jobs at any age. Recent college grads can't all be wrong. :)
2) There is always a strong reversion to mean
3) Most of the people in their 50s or 60s whom I hear complaining were an outlier for employability for their age group in their 20s and 30s (e.g. straight out of Stanford).
Most older people I know are /very/ employable, and don't complain. Another pathway:
- Finish a state college. Have a very hard time finding a first job.
- Work up the career ladder, and build up a resume, reputation, and track record.
- Much easier time finding jobs in their 50s and 60s than straight out of college or early career.
Some of this also has to do with bust/boom cycles. People who entered the workforce during recessions had a hard time finding a job in their 20s, and then found things comparatively easy. People who entered during a boom cycle are the opposite.
Ageism might still exist but significantly pushed back.
A lot of life now is ordained on the idea that we don’t live forever and we can’t see change in our lifetimes… but if the lifetime is forever - well, I’m gonna fight to make it better immediately cause then I have forever to enjoy it.
Where I live, no one struggles to buy insulin. And if there is any kind of anti-aging treatment available, I don't doubt it will be offered to the general population without much ado. Compared to the rising cost of the pension systems in aging populations, treatments like that would be probably "dirt cheap".
When anti-aging becomes real rather than fantasy, there are going to be so many mutually incompatible conspiracy theories.
You're assuming the rich are rational. The billionaires on the OceanGate Titan didn't think this way; they were perfectly happy to beta-test a shoddily-designed sub.
(The recent explosion was such a test).
(And that sub had apparently been to depth before? I didn't follow the details…)
I think the OceanGate disaster just shows that billionaires aren't any smarter or more rational than the rest of us.
Also I don't see what would be to gain to not do it for those in power.
I’m sure a lot of people would defend the arrangement. “Of course Elon Musk can have inmortality and you don’t. He’s a genius”.
Don't judge the prospects of the entire humanity by the pathology that is called the US healthcare system.
Bezos would be the guy, spending billions on Altos Labs.

Based on the rates of various types of accidental deaths, you could extend that quite a bit by avoiding dangerous drugs and and living in an area where you're unlikely to get shot. If we figure out really safe self-driving cars, that'll make a big difference too. In much of Europe you can already get the same effect by taking public transport everywhere. Air travel is quite unlikely to kill you.

Put all that together and a 10,000-year expected lifespan looks pretty achievable.
In addition some cells reproduce only a few times, often only during youth.
And there is sometimes involution like in thymus.
No some cells never reproduce, for example motor neurons.
> "I imagine that if aging can be reversed new cell growth could also be stimulated."
I have a hard time to imagine how to replace a up to one meter/yard long cell with sometimes hundred of synapses which is surrounded by cells such as astroglia and microglia that are equally important.
