Elon Musk Wants to End Mobile Dead Zones (There’s a Big Hurdle)

Elon Musk is a master of promoting new technology ideas, but of course not all of them come to fruition.

Yes, Musk’s Tesla (TSLA) has become the world’s biggest EV maker and most valuable automobile company, but that hyperloop thing has really fallen by the wayside. And Tesla’s full self driving software is still in beta. And of course, nobody’s even seen a Cybertruck in the wild because they’re not going to start making them until next year.

Such is the fate of visionary disrupters, of course. And overall, it’s probably fair to admit that Musk has delivered on a lot more ideas than most people have even had.
