        The conventional Internet is currently like a system of roads

        you still can use the roads (e.g. send emails, or browse
        websites) your vehicle might get hijacked, damaged, or long
        arms might reach into its back and steal your items (data) to
        use it against you and sell it to others - while you can't
        even notice the thievery nor accuse and hold the scroungers
        accountable.
	<!-- Proposal from Fabian Gerlach: The conventional Internet is currently like a system of roads 
	with deep potholes and surveillance cameras all over the place. 
	Even if you still can use the roads (e.g. send emails, or browse

	cameras will create a movement profile about your life: They 
	recognize your car license plate, track you everywhere you drive,
