I want to expand a little bit:
It is eugenics if it works, and if it does not work.
As it stands, so many animals did not survive animal testing. It is nowhere near ready to be used on people. The FDA fucked up big time and people will probably die, especially those that doctors do not give a shit about and are getting desperate for help. It's not going to be just cryptobros and Elon's bootlickers.
You want to know how I know?
If it wasn't done by Elon Musk, I may have considered it for my photosensitivity. The website for the company has no mention of Elon. Neither does their twitter. LinkedIn might have it, but this is important to know because of his direction with Twitter and Spacex (Remember? Rocket fucking exploded?). People will be put off by his name being associated, and they know that.
Let's say it worked by a miracle, for argument's sake.
Disabled people would be pressured to get a surgery they may not even want. It will be sold as a "cure" for any disability. Anyone who rejects it will be seen as wanting to be disabled.
It can be taken advantage of really easily. Shit goes wrong in IT all the time. I work on an IT helpdesk for a huge company for fuck's sake. Who is going to afford the chips? Who can they be serviced by? It's another bid for a monopoly from Musk because I will promise you that they will come out of it like Apple with intentionally hostile design. You are handing control of the most crucial organ in your body to a company- and even that organ is not fully understood and can unexpected things happen. There's no fucking IT helpdesk for brains.
Do not get it. Discourage anyone from getting it. Encourage people to look into self-advocacy or self-diagnosis to keep anyone from this quack doctor.
