[Bloat] [Starlink] On fiber as critical infrastructure w/Comcast chat

Read the arguments on potable public water supplies. You're missing the forest per the trees.

Also, Comcast offers full wifi services. The dmarc at the property line and right of way is artificial. 

The economics is a 100gb/s sfp. Not 2g  or 6g. I'm asking for a roof of shingles vs a thatch roof. Many may laugh until they realize we're talking about real life issues. A 100Gb/s link drives queues to empty. Compute moves to speed of causality. That's the best we can do today and it'll be the best done in 50 or 100 years from now, assuming the optics are pluggable.

We need to stop conflating capacity with latency. Doing so is a basic engineering flaw.

The fiber has basically infinite capacity.  Where it ends, where it starts and who gets to decide on the optics is a non trivial problem. And that choice matters. But hey, many men think it's their womb too, which is no longer funny.

I want 6 Gbs optics. You laugh. Comcast says I can't have it. Why am I not in charge of this choice?
