No, I primarily mean new ways of treatment. For example, a hypothetical country which can easily cure Alzheimer's would have much lower costs of medical care for the elderly. Being able to cure (as opposed to control) diabetes, a large variety of autoimmune disorders, etc. has the potential to greatly improve the efficiency of health care.

I see. But the point is how much disability people will have before they die. It's not obvious to me that it will go down, at least it has gone up in the recent past.

You're basically claiming that there will be no major breakthroughs in the foreseeable future

I'm claiming that breakthroughs which increase the amount of available energy or other scarce resources by a huge amount don't seem especially likely in the foreseeable future.
