We shouldn't beat around the bush. Musk has shown very few times that he has any idea what he is talking about. His tweet sounds identical to some middle manager's sentiment you'd get at some huge conglomerate trying to make a name for themself after taking over a group.

And it should be noted that he's responding to another tech billionaire who fancies himself as an oracle as well. This is like throwing around verbal spars at the water cooler at the local squash club.
