Elon Musk is not a shape rotator.
Elon is baffled by the 3D world because it doesn't fit neatly into his linear 1D mind. He copes by pretending he finds the mystery wondrous. The only reason he doesn't look entirely retarded is that his V-IQ does happen to be high, so the 1D lines can sort of simulate complexity by getting very long.
P.S. The actual IQ you want is not S-IQ nor V-IQ, but L-IQ. They almost never talk about it, for the usual Envy reasons. It doesn't matter how fast you can do sums if you can't understand what they mean.
