Re: Musk is like a bright light
Musk has pushed the world forward massively. He made electric cars cool, as well as advancing the technologies involved, and has contributed to both the space race and renewable energy.
He is getting to a dangerous point though. He is starting to believe his own hype.
Hyperloop is potentially dangerous, as if any of the tunnels or pipelines the trains travel along is breached (and if they run above ground, they will be), the entire system is likely to implode at the speed of sound.
The Las vegas loop (and his planned network of tunnels under major cities) don't really solve the problem of traffic (how can they, they involve more vehicles), and have the same problem Metro builders have under major cities. Namely that there is already a lot of infrastructure under the ground in major cities like London, which limits the number of tunnels that can be built. Apparently, their brand new tunneling method is not actually as cheap as Elon makes out, and is considerably slower than existing methods,
Also, the tunnels in the LV loop are barely wider than the cars. It's likely to be almost impossible to escape if something happens to one of the cars and it catches fire or explodes. Existing train systems do not have that problem because there doors don't open outward. The tunnels are also generally wide enough for people to pass alongside the train. Even if they weren't, the trains generally have exits at the front and back.
Starlink looks like it could be good, but I'd need to see evidence that it's not just going to be used to enable the social media companies to track the few people they don't.
As for the robot, I'd like to see evidence that what they've demonstrated isn't a dancer in a suit. At least Boston Dynamics have shown actual robots doing stuff.
The truck, from what I've seen, the range as it is is too limited for lot of use.
