The viability of hyperloop is nil. It doesn't exist. It is literally physically impossible for it to be viable. I think it's on-topic whenever hyperloop is on-topic.

Okay, great. It's on topic. So what? Why is hyperloop's viability nil and nonexistent?

That's been well covered elsewhere in this thread and other threads.

I'm not going to say the claim it's not viable is original, nor am I going to argue that claim. But it is on topic.

Yeah, Elon Musk never thought about that because he was busy landing rockets. Come on.. why do you think he did not think about that? By the way, curves in the track can eliminate this when they can slide a little. And I can imagine there are more and better solutions.

Just like how all those experts at Tesla had no trouble scaling up mass manufacturing.

Nah, the Dunning-Kruger thing applies equally well to Tesla and SpaceX. He had no experience in either field before starting those companies. It's just that he has, in spite of all probability, succeeded and so you see them in a different light.

Didn't he actually design the first rocket himself? He's quite smart. I don't think "industry experience" counts for much. By the way you're using "Dunning-Kruger," it's unclear that you actually know what it means...

I just Dunning-Krugered myself about Dunning-Kruger.

Out of curiosity, have you ever built anything big? I say this because the tone of your comment is dismissive, however it seems quite low-effort. I can translate your criticisms into criticisms of building subways in 1863: - if you build a subway it will be the biggest underground railway ever built. - Rocks. They could fall in front of a subway car and cause a huge accident. - safety. what if all the lights and powe…

Also, planes are a terrible idea. I mean how do you evacuate people from them if something goes wrong? I think this whole airplane thing is just vaporware.

That isn't exactly a solved problem though. Almost all of the time it's "everyone dies". We just have failure rates low enough and it's convenient enough that people accept it.

While what he has done should be commended, I don't think it's fair to say that he "started from nothing". His own mother was an entrepreneur, obviously not as successful as him but come on, he went to a "prep school" for goodness sake[1]. 1 - https://en.wikipedia.org/wiki/Richard_Branson#Early_life

The point is that he built his businesses from scratch, and did so with a significant learning disability that meant he struggled to understand even basic P&L statements and balance sheets. His mother didn't build his record store or record label. His mother didn't build his airline. His mother didn't build his brand. His early business successes were built from nothing. They weren't seeded with millions of dollars.…

On the other end is the absurd notion that someone who starts with a (comparatively) huge cushion or even more is "self-made" in any meaningful sense of the term.

Take this example: Bill Gates as compared with Jan Koum. Applying the label "self-made" to both of them is nonsense. There's nothing "envious" in pointing out that one had a lot more going for him than the other.

i would very much doubt that. i remember reading an article early on about some russian investors or engineers noting he knew almost nothing and that he was just reading a lot of university textbooks on areospace engineering.

Something I wrote a while ago.... w/ back of the napkin calculations....... Why I wouldn’t invest a money into Hyperloop - Stabilizing a single fault line risk pylon is more than $250K. - How many million are needed for vacuum pumps to evacuate 100+ million cubic feet of of pipe to 100 Pa? - Hot air discharge needs to go somewhere. For every 1 bar pressure, you need ~200 to ~400 cubic meters of volume which is larger…

I don't think it's right to use figures that can change to disprove an Elon Musk concept. If you did that back in the day, you would say there's no way Tesla could work because the cost of batteries is prohibitive and the supply too limited.

>I just Dunning-Krugered myself about Dunning-Kruger.

Ultimately you didn't. That very comment shows you were able to recognize and correct for your mistake in the end.

Perhaps if you insist you've Dunning-Krugered yourself about Dunning-Kruger, then I may agree that you have in fact Dunning-Krugered yourself about Dunning-Kruger.

It's turtles all the way down.

This is the real insight.

Everyone has been chuckling about electric cars and private rockets until recently, and that was by experts in the respective fields. Chuckle all you want.

Go here and scroll down to "Select historical production vehicles" - https://en.wikipedia.org/wiki/History_of_the_electric_vehicl... I grew up in the 70s and saw production electric vehicles that are not on this list. People have been chuckling for a long time and for good reason. It's not that electric vehicles won't eventually be successful -- they must. It's that the time from, "Hey, an electric vehicle would be a…

Let me be clear. I was talking about criticism of Musk specifically. Pretty much EVERYONE in the aerospace industry thought he was nuts, and yet SpaceX made it to orbit. Even a couple months before their first stage landing others were saying it was impossible.
