I'm no fan of Elon at all, but at least most of his endeavors amount to something like "haha look at the funny rich man" at worst. Neuralink on the other hand is giving me proper existential dread. I can't decide what's going to be worse, it working or it not working.
If it doesn't work they are gonna be essentially maiming a bunch of people to figure that out. If on the other hand it does work we're only a short road away from ads on the inside of your eyelids and other such dystopian technologies.
I'm no luddite, but it'll be a cold cold day in hell when I let anyone implant tech in my brain, let alone Elon Musk.
