This makes the Hyperloop concept feel vastly more feasible. And manufacturing
carbon fiber at those scales will open up all kinds of new
infrastructure/architecture possibilities. The biggest question on my mind is:
how does one continuously infuse/cure epoxy?

Hmmm. I'd have to see this run through an earthquake model. It seems to me
that having them stacked/connected vertically would cause problems during an
earthquake.

Think about those coffee stirrer straws that look like a figure 8 (it's a
single straw pinched in the middle): if you hold one between your fingers the
range of movement left/right is easy but an up/down movement is quite
difficult (and if you push hard enough the straw buckles).

There's usually significant vertical and horizontal displacement during an
earthquake. My thinking is that Elon's original design would fare better.

Building the structure is the least of the Hyperloop's problem.

How about supporting near-vacuum on such a large scale?

How about dealing with earthquakes, erosion, landshifts, where even a small
shift in a section of a tunnel would mean instant death for the travelers.

How about obtaining the land rights to build it between SF and LA?

Regarding ground changes, we can look to current bullet-train rail systems.
Nobody has ever died on a bullet train in Japan due to earthquakes. I saw on a
documentary that Japan feed seismic sensor data into train control centers
where any dangerous seismic event would trigger automatic stopping of the
trains.

I never said it's impossible, I think it's a much bigger problem than building

How is it a bigger problem if it has already been solved today?
