I thought that at the speeds they were talking about they would even need to worry about dust but this picture shows what looks almost like gravel at the bottom of the tunnel.
Did someone use this thing for sludge storage because those look like flood water deposits?

The tunnel is totally unfinished, that rail system is only for moving the rock sludge stuff out.

I think the tunnel was also made with largely COTS components, so it's not a proof of concept of magic Musk boring tech. It's mostly just proof of life from a company that might do something cool in the future.

Great news on many fronts. If they can get that going for every organ that is pretty much step one towards immortality, the second step would be finding a way to keep the brain healthy. Future iterations for the rich will be brain transplants into a new body every 18-20 years, stopping and reversing the aging process, and figuring out how to harness cancer for straight up regeneration. If we haven't start terraforming the moon, Mars, and the asteroid belt by then we'll pretty much run smack into a class war as overpopulation sets in. Probably be a quick one, though. Nuke, nuke, nuke, and the rich come out of their Fallout Vaults once the radiation goes away. It only takes a few thousand people to keep enough genetic variation going to perpetuate the species.

Nuclear weapons? At that stage of technology, you would not need Nuclear devices to wipe out the world. All it is going to take is an aerosolized form of nanotechnology. Spray it and inject it into the air and all water supplies on earth. Program them to remain inert inside the human brain until activated. Then when the time is right for wipe and control, activate them and give all the people you want brain aneurysms. Population control complete.

At the moment, Drexler-type nanotechnology is synonymous with fantasy magic. Your nanotech aerosol is on par with "I will curse the earth".

(by the time it might be a threat, you get the world of "We Were Out of Our Minds with Joy", where the American Legion instakills you on the slightest suspicion of nanofoulplay)

Bizarre Particles Keep Flying Out of Antarctica's Ice, and They Might Shatter Modern Physics

There's something mysterious coming up from the frozen ground in Antarctica, and it could break physics as we know it.

Physicists don't know what it is exactly. But they do know it's some sort of cosmic ray — a high-energy particle that's blasted its way through space, into the Earth, and back out again. But the particles physicists know about — the collection of particles that make up what scientists call the Standard Model (SM) of particle physics — shouldn't be able to do that. Sure, there are low-energy neutrinos that can pierce through miles upon miles of rock unaffected. But high-energy neutrinos, as well as other high-energy particles, have "large cross-sections." That means that they'll almost always crash into something soon after zipping into the Earth and never make it out the other side.

And yet, since March 2016, researchers have been puzzling over two events in Antarctica where cosmic rays did burst out from the Earth and were detected by NASA's Antarctic Impulsive Transient Antenna (ANITA) — a balloon-borne antenna drifting over the southern continent.

This is long but good. Stuff on consciousness. If it's right it pushes brain emulation out 100 years or so.

seems to me to be a general misinterpretation of standard chemistry, biology and physics. it's been quite conclusively shown that consciousness is an after-the-fact rationalization of pre-determined responses to stimuli put in a social context. some people don't like it and, like this guy, try to rebel against the fact that we are all robots engineered for social savvy. he doesn't approach the subject of false memories, self-deception and social rationalization because they easily undermine his argument. him trying to liken a single-cell eukaryote to the synapses in the nervous system is another example of not understanding the underlying chemical mechanics of the situation. he asks if life derived from pi resonance in important carbohydrates, which it did just as much as from other electron interactions.
