Humans Who Dream Of Companies That Won't Need Us

Sounds like the first chapter of Accelerando.

What I don't understand about the Blockchain hype (and I say that as a fan of Bitcoin): isn't the primary problem it solves the avoidance of double spending?

Or in the case of Ethereum, perhaps double contracts. But still, the issue seems a bit overblown to me: to double spend (or present fake contracts, or more generally, fake data), you somehow have to isolate the victims network before injecting the fake transaction into it?

Sharing data in a p2p network was possible before the blockchain. Maybe a lot of applications don't really need the bullet proof security of the blockchain to exchange data?

I don't see the real advantage for a self driving car company, for example. Why couldn't it just as well live on a server - maybe in the cloud so that it has backups? The issue of cheating could be countered with trust, just as normal businesses do (screw over your customers too often and they'll stay away).

The real problem seems to be political, I don't think it is legally possible to instantiate a business without human background?

Suppose I launch a contract on Ethereum that tries to buy a self-driving car and rent it out to passengers. How would that car get a license plate? And without it, wouldn't the police quickly remove it from the street?

  >  At some point we must get rid of all the humans on earth to keep up economic growth.

Sure, but first we need at least few colonies to move to.

Companies are simply a tool that helps a group of people to make a profit. If you remove the group of people then what would be the point?

Not-for-profit companies shouldn't exist then?
