#2This has been going on for several years at least. These are some pretty good articles from some amateur sleuths:

#3So if glass slows the signal down, would it be possible to use a hollow fiber?

Microwave is traditionally used to reduce latency caused by fiber’s refractive index. I suppose you could bury waveguides, but an air interface works just as well (besides the occasional weather; better to be fast most of the time).

Or a much thicker fiber with conductive coating while sending microwaves through it? Shorter microwaves should be transmissible via a few mm wide conductive pipe.

I can assure you, that link already exists several times over. There are dozens of links between Aurora and 350 E Cermak, and dozens more between 350 E Cermak and Cateret, NJ. There's even an entire ISP based off the lowest latency link between Chicago and New York.

#8It's weird that we've set up a stock market for machines rather than humans, where ever-faster bots interpose themselves between slightly slower bots, all the way up to the original buyer and seller, who are probably bots as well.

The machines help humans. The bid/ask spread on a $100 share in 1970 as $5. Now it's $0.003 cents and it will continue to narrow, saving you and I money.
