That’s not a strong value proposition though. There are many specialized devices for disabled people - doesn’t mean that they offer great value to the able-bodied. Eg a special watch for the blind is a great idea… but not something that would attract many non-blind people.

What a strange argument. You might as well say penicillin doesn't have a "strong value proposition" because it doesn't have value until you're sick.

That seems like a poor counter. Everyone gets sick as far as I know not everyone becomes disabled.
