But regarding their testing, it was certainly a small scale test of known technology, but you underestimate the value of such tests. There's massive amounts of theoretical aspects they have to plow through first, move gradually to small scale live tests and finally piece it all together in one big PoC. After the small pieces are theorized and tested, it takes exponentially less time to piece them all together in the end.
I wouldn't say I underestimate the value of small-scale tests so much as I would say that Musk and company have been deliberately obscure about exactly what they were testing, and have been downright misleading about the distance between where they are now and what they claim they will be able to deliver. We were shown a dog-and-pony show constructed to meet an artificial publicity deadline, not a well-explained demonstration as part of a clearly-elucidated development roadmap.
When I read comments like yours, it reminds me of anti-innovation corporate voices I have to battle against on a daily basis.
Hmm. Do you misrepresent your progress and conceal the nature of your accomplishments to your corporate masters too, then? That could be your problem.
Look, I'm a scientist in an academic setting, but with private-sector collaborators. I do both "pure" and "applied" research. I contribute to both peer-reviewed papers and patent applications. I can tell the difference between healthy skepticism and blind anti-innovation. The problem with Musk's Hyperloop demo isn't the idea, or the technology, or the dream--it's that he doesn't tell us what the demo is actually doing. It's like writing a scientific paper that starts with the usual Abstract and Introduction, then jumps straight to a one-liner Conclusion and a big Discussion about the implications of the work and all the cool stuff that's going to happen in the future. He just skipped over the Materials & Methods and the detailed Results. We aren't told what we're actually looking at or what it can really do, just to take on faith that it's awesome. That's my issue.
