I get excited over the personal computer: lap top, tablet, smart phone where level 5 is daunting.

Think of those Amazon data centers with racks of computers with the data and code of organizations that would like to sell access to data and function to each other. Level 5 is then a thing carefully negotiated in a contract.

Imagine a computer monitoring the situation in some sort of power plant. Level 5 is actually simple there.

For the computers in a car; I don’t want to think about that today.
