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.
Well this really exists for those billionaires and rulers. This isn't for the common person.
They're so mad that they've removed themselves so far from us and we still share a common experience in death. That's unfair for them to have to be associated with peasants in such a debasing way. So now they'll remind us that death is for the poor or at least not living centuries will be for poor.
I have never understood people who make this argument. In all of history, can you point to a single time when technology wasn't eventually commercialised and made available to the masses at affordable prices? The billionaires don't want to keep it to themselves, they want you buying more stuff from them.
