Sleight of hand businesses? Only Pay Pal was truly successful. The rest are a conglomeration of already existing ideas, some dating back decades, but repackaged as Musk originals. Its an embarrassment to use the name of Tesla, a great inventor. Hypertube = Vactrain (1799). EVs = 1832 (Robert Anderson). Even the battery systems are not Musk's they are Panasonic's. Where Elon has been successful is creaming idiot politicians into forcing other real manufacturers to pay Musk, and gaining billions of dollars in grants/subsidies, then going off to China to cream the same thing there. So Bernie Madoff must have been a successful businessman too?
