"so where is the value?"
Faded and almost gone. To give Tesla their due, they did bring EVs into the public consciousness and scared the incumbents into rapidly accelerating their plans. Without Tesla, I wonder where the EV market would be today? Probably years behind the current position. But Tesla have screwed up badly, what with starting out buying up a minnow and not having real car manufacturing experience so their expensive cars were plagued with issues and they never really got past that while the incumbents, with generational and institutional experience in the market adapted and are now eating Teslas lunch.
