The conventional Internet is currently like a system of roads with deep potholes and highwaymen all over the place. Even if 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. The Internet was not designed with security in mind: protecting against address forgery, routers learning metadata, or choosing trustworthy third parties is nontrivial and sometimes impossible.
