Cures are not perpetually profitable. Only treatments are.
Well that's a particularly cretinous argument. Purely from a profit perspective which is better for doctors, hospitals, "big pharma" and insurers - a dead kid or someone who is cured and goes on to live another 70 years, requiring all kinds of medical interventions during that time not just for himself but for any children he may have?
It is for this and a multitude of other every day scenarios that it is unlikely a vehicle like this is coming any time in the foreseeable future. Self drive will most likely mean advanced driving modes, which might include hands free driving in some limited and controlled circumstances. It will also most likely require a conscious and unimpaired driver behind the wheel to take over at very short notice.
I assume anyone could run such a service although it would be predominantly used for money laundering and therefore instantly attract the attention of law enforcement. Zero coin sounds like pretty much the same idea but in a more distributed way, to allow people to exchange money for a token and then redeem that token later, separating the transaction chain.
And as one of the few people who actually used OtherOS, I still completely understand why they killed it.
