Is Elon Musk an earthling?

But, if it is theoretically, a safer, faster, more efficient means of transport, then I'd say we should get into it.

Let a thousand flowers bloom, and all that. There's no reason not to explore possible new technologies, and at some point, we will have to take the plunge and build something sizeable with it.

What I don't think is a good idea, is sinking billions into it without having first checked whether it's even seriously feasible, let alone cheaper and better than the alternatives.

After all, monorail was once the future.
