Have you ever seen firsthand a person in the final stages of Alzheimer's disease? If life is so precious to you that you are willing to exist for eternity in such a state, far be it from me to tell you otherwise.
May you enjoy the outcome of your choices.
Presuming you would actually live in such a state even - perfecting this technology will require other ground breaking research, some of which might be able to handle Alzheimer's.
Sure but questions arise:
"How much mental trauma/cognitive damage can a normal human mind sustain before it is no longer capable of comprehending its choices (or even the concept of "choice") at all?"
"Will the brain-in-a-vat scenario exceed that limit?"

As I alluded to before, is it possible to unscramble an egg?
You are not. I am.
And I choose to live.
