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.
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.
Maybe the procedure would fix whatever's wrong with their brains. Like, maybe Trump would slowly regain the ability to form complete sentences. I'm imagining a Flowers for Algernon situation where he wakes up one day, reads his own Wikipedia page, and is briefly ashamed before the non-neural parts of his body crap out.
