I was with ya until the hyperloop example. Hyperloop was pushed for years as a vacuum tube train. Serious prototypes of this were developed. If it had worked out absolutely perfectly, it would still have lacked the throughput to be a good idea, but the prevalence of earthquakes in its target area, the inherent instability of a vacuum tube, the massive intended scale of the system, the economic feasibility of digging a huge tunnel, etc all made it an absolute shitfest of an idea. They then came up with a new idea, which was a one-lane tunnel without a safety walkway, which is utterly useless for passenger transport because it has, at best, the throughput of a two-lane highway. The hyperloop is probably elon’s most embarrassing failure after twitter.
