@beffjezos I say both energy and mass, as they are separate scarcities for practical purposes, despite being technically “equivalent”, as described by Einstein’s famous equation.
Our solar system has only a tiny percentage of non-solar atoms with which to build things.
As usual, legacy media is misrepresenting the situation.
I just asked Tesla & SpaceX to try out Grok 4.5 to see if it solves their task, not use it no matter what!
They should continue to use other AI models if those models outperform Grok.
