For me, the big advantage is that electric cars can be charged from many root sources including solar, wind, and nuclear. These sources can be sourced locally to one’s home or at least within the country, which reduces the perpetual excuse for wars to secure access to fossil fuels. That’s a significant contribution and Elon Musk is largely credited with moving the auto industry in that direction.
Also, I like his Don Quixotic nature. Charging forth into areas despite the naysayers and avoiding analysis paralysis by taking action and accomplishing some amazing feats with a team of people of course. We have enough tepid “leaders” who just want to copy other money-making ideas with easy fed money distributed by simple-minded venture capitalists.
He’s doing some things right. I am personally getting a big bucket of popcorn to watch what he does with Twitter and how he’s going to deal with all of the attacks from the government and individuals that are frightened of human beings expressing themselves more freely on Twitter.
