Damon Lavrinc of Wired relates the improbable:
Elon Musk wants to revolutionize transportation. Again. The serial entrepreneur envisions a future where mag-lev trains in enormous pneumatic tubes whisk us from Los Angeles to New York in 45 minutes. Need to be in Beijing tomorrow? No problem. It’s a two-hour ride away.
It’s a great idea. Unfortunately, there’s pretty much zero chance that anyone will ever have any motivation whatsoever to spend hundreds of billions of dollars on it. I’m afraid that it might be a long, long time before our species progresses in any way which is not immediately, massively profitable to the few people holding the Capitalist purse-strings.
