Test hyperloop track was supposed to be build close to where I live, in Antequera, Andalucia, Spain. There's a railway test center built specifically for testing new rail technologies. Since it was build decades ago nothing was really tested there because bullet trains already existed and no one had any new designs since then. The trains didn't really change since 1980s. At the same time bullet trains still lose to planes on longer routes because they are simply too slow. Hyperloop was supposed to change this and offer rail technology that would compete with planes on long routes. It was supposed to be the next step in rail travel that would be able to compete with air travel. Now we know it wasn't feasible but just because it's not right for USA it doesn't mean it's not worth testing.

Even more material for the "words you have been using wrong" thread.
Again, maybe it is but you can't really be sure until you design it, estimate the cost, try to lower it by modifying the design and if it's close try building some prototype to test it. People keep talking like you can evaluate design like this on a napkin. That's just not how engineering works.
Ups, thanks. Totally missed that.
Yeah, that's why we don't have any thousands mile long tubes transporting dangerous substances. Oh, wait. We do! What happens when someone shoots a gun at them? They go to jail! (look up Daniel Carson Lewis of Livengood).
In your theory, why can't the same laws protect 'railway tubes' that protect oil and gas pipelines? Why terrorist don't shoot guns at pipelines all the time? Why don't terrorist jump on high speed rail tracks and sabotage them? Where I live there's 5000 km of high speed tracks that are not "actively defended". There's just a fence. Big rock could take out a train. Why do you think no one ever attacked it but everyone would be shooting at hyperloop pipes for fun?
Oil pipelines are often buried underground, they can have up to 60'' in diameter. Hyperloop pipe is about 90'' in diameter. It could be feasible to put it underground. I'm not saying it's a good idea or bad idea. I'm just saying that some guy commenting on a blog is not a good reason not to try. Get enough of good engineers to work on it for a while and you will know if it's feasible or not. That's what they did. I think it was a good thing to try.
You made the exactly same false equivalence between gods and computer simulations. That was my point.
"We know simulations can exist, since we simulate things, so it stands to reason that since simulations exists on earth that it could exist somewhere else. Nothing about simulations conceptually requires anything that we don't already have a scientific method for. "
Simulating entire world only requites different computational scale which we also know is possible because we keep improving our computational capabilities.
Ok, so you also don't believe there's any extraterrestrial life in the universe, right? And it's as likely to exists as Norse gods? I mean, there's no proof for it after all.
Why being in a simulation is unlikely? How do you estimate the probability of that?
The "belief" we're in a simulation is more like a interesting idea than something people organize their lives around. Is it possible? Yes. Am I going to praise the great programmer every Sunday? No.
The belief in God in most cases is not just belief in some general higher power but a very specific deity with weird morality, silly mythology and bunch of scam artists behind it.
- I think there's a higher power...
- Ok...
- that got mad at us for eating fruits but then impregnated a lady with itself and pissed us off so that we murdered him and he could say he's not mad anymore.
- ... WTF?
The simulation doesn’t respond to prayers or requests.
How do you know? What if the guy running the simulation actually monitors what we think and reacts to it? What if the personally decides to give people cancer or cure it? What if he copies our minds to simulation of hell after we die? What if 2000 years ago he copied himself into the simulation to get crucified?
Yeah, I wouldn't really trust any of that unless it came from interdisciplinary team of engineers that actually looked into it. I know that there's a lot of bloggers and youtubers that like to shit on every new idea but they are often wrong and are simply trying to create clickbait content.
