> What sort of screen readers are available for the dead-blind?

None at all, even though the dead-blind greatly outnumber the living-blind. This area is ripe for technological disruption.

Oops, should be deaf-blind. But you're right: I may have accidentally stumbled upon a market that, apart from cryogenics, has nearly zero products marketed toward them. And what of the living? Why can't they get the whole "dead" experience without the full commitment? I see DaaS (death as a service) with monthly subscription as a completely untapped pool of demand.

It feeds it into a single line of braille they can read. You can imagine why any complicated site becomes an extreme pain to interact with.
