Okay you've now helped every paraplegic on earth.

However every human being in a capitalist system from now until the sun engulfs the planet is a slave unable to ever break free due to brainwashing, surveillance, and control chips implanted in all humans within these societies to prevent revolt. This is forced with economic coercion and later done at birth as an "equality" measure since you can no longer work, get benefits, etc without one.

You've made a small number better but doomed humanity to be a slave race. Good job. Not a worthwhile trade off.

Such a thing should exist under communism but under capitalism it will be used to design unbreakable chains to subjugate humanity to the end of time and that and the suffering it will bring is unacceptable.

This is why I view even Chinese efforts as terrifying. Their research will not stay in China, it will be taken by the west and used in horrendous ways. Man is not responsible enough yet to have this kind of technology.
