Besides, what does it even mean to have “another” internet? Even if you could build something entirely separate, all it takes is one person bridging the two and now you’re back to having one large network. You could use different protocols to transmit data but then you’re using the same underlying infrastructure which makes the concept of separation more philosophical than physical.

We only have the one so, yeah, obviously.
