Comment on 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.

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.

That’s nothing to do with the back that clone is impossible and just that cloning is hard. You are acting as if it is an unsolvable problem.

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.

I’d be fine with billionaires getting it first. As much as I’m not a fan of late stage capitalism, I refuse to cut off my nose to spite my face; they got A/C, feather beds, cars, baths, and all sorts of other luxuries long before us plebs got them. Let them beta test the stuff, and by the time the economies of scale pick up enough for it to be affordable to the rest of us, the kinks will be worked out.

Of course there’s always the possibility of a cartel withholding it from the masses, but that’s what the second amendment and guillotines were invented for.
