99.67% of seawater can't be used for fusion. Some very poor napkin math, that's around 1.3 million cubic miles, with around 2200 cubic miles per inch of sea level, which is around 600 inches, or 50 feet drop in sea level if fully depleted (not including any sea level rise from global warming).

Is this fundamentally from poor routing from infrequent use? For example, if usage was 50%, would the routing/hops between the two somewhat converge? Or is this actually a "v6 is hosted on a separate server somewhere else" type problem?

This is a very hard problem, when working with china, in any capacity. There are whole teams dedicated to this, in larger companies. Usually, it involves IQC where you sample the devices, X-ray them, and verify things are correct. There's also neat thermal methods: https://ieeexplore.ieee.org/abstract/document/11038103

The same link shows that a video was also put on his CD in the 70's!

And, there's LaserDisc, of course (although analog, unlike the digital disk in the above), which was somewhat of a flop (the ridiculous dimensions being part of the cause).
Tangentially related, BlueRay was more about just waiting for a blue led to be invented, than some new disc tech! [1]

I flag all political submissions because reddit already exists.

My digital calipers can display freedom fractions. It makes my eyes bleed.

I know little of this. How/why could one be higher latency over the other?
