This researcher wants to replace your brain, little by little. The US government just hired a researcher who thinks we can beat aging with fresh cloned bodies and brain updates. (www.technologyreview.com)

If you want a bit of a deeper dive, Sean Carroll's Mindscape gets into the science of aging and known workable remedies/treatments.

The good news is that Billionaires will not be living forever any time soon.

The bad news is that we've got a cellularly defined terminal limit and there's nothing we can do to simply reset the clock. "Cloned Bodies" for animals are dysfunctional bordering on nightmarish. The human brain's plasticity isn't something you can renew with a pill or a potion. Blood Boys don't work. There aren't trivially replaceable components in the human body.

Its wild this research is even being attempted, its borderline unethical to experiment on otherwise healthy people.

I fully don't expect immune system driven aging to be understood until the Thymus better understood. DNA reproduction and telomere related aging will not be addressable until cell to cell signaling is finally mapped, and methylation activation/deactivation can be targeted.

Most likely some kind of cloned brain tissue can help reduce age-related cognitive decline and some diseases. Imo we'd get far more out of targeting specific diseases than going after aging.

Yes, because who wouldn't want to live for centuries amidst floods, fire, raging mad politicians and greedy billionaires...

No. Absolutely not. Whenever anyone says, "wouldn't it be great to live forever" remember that means people like trump and Musk are with us forever. Unless people take things into their own hands, but that's another issue.

means people like trump and Musk are with us forever.

But that would also mean their polar opposites would also be with us forever, the objectively best of us

they tried that a few years back via a quadraplegics brain transplant to a normal body. he died on the table. not likely to change that with cloning
