Is the following a good analogy?
1. The Internet aspires to be neutral infrastructure for communication.
2. Permissionless blockchains aspire to be neutral infrastructure for computation.

how is captured the consensus aspect? a single computer isn’t also a neutral infrastructure for computation?

A single computer is owned by someone. Permissionless consensus is the justification for viewing a blockchain protocol as a ownerless (i.e., neutral) computer

ok I didn't interpreted "neutral" as this, interesting!
