I work as a disability support worker, I have clients in wheelchairs and traveled the world with them doing sport. I am fully aware of what cutting edge tech can do to better lives, and I am even more aware of what the effects of not having access are.

That said, your argument is nonsense. These companies have more money than they know what to do with, and the trials of these products in humans are intentionally small. They have an obligation to do no harm, and that includes supporting their patients til the end of life.

If that requires slower trials, or special insurance the company pays to cover these things, or careful standardization so the torch can be passed on should the company go under, so be it.

The people who got the ocular implants are going blind again one by one because the company that gave them vision went under. They cannot get support or parts.

Can you imagine having your sight and therefore independence again, only to have the cold fear every night that you’ll wake up and your implant won’t be working?
