Elon is basically moving in circles, I doubt if he even knows what he wants anymore. Bitcoin energy shit haven't even been taken care of and here he is saying shits again.
My take is that all this talks on energy usage reduction or an embrace of green power are font up lies, put in place to help Elon regain his social status.
We have to live with the reality that people like Elon Musk are inevitable part of the crypto currency ecosystem. They would influence, users and masses at large to buy bitcoin and other crypto currencies.
