Great write up. These are the steps that make adoption "difficult". Not that it's hard, per se, explained very well here in fact. But these are steps that aren't necessary on more commonly used networks. Having to explain that "all" is not actually "all" always feels wonky.
The fiber is there because the data is being sent through the fiber as photons like usual. There is no zero latency happening at all and it will not allow rovers to be controlled remotely in real time. That would break causality. This has more to do with encryption and the inability to wiretap without detection.
Believing in inferior DNA would put you in better company amongst them than merely being born. Food for thought.
