Nit：The word “orthogonal” should not mean merely “different”. It should mean “completely unrelated” if we are drawing a proper analogy from linear algebra. Orthogonal vectors have a dot product of zero. No correlation whatsoever. As ML and linear algebra terms spread to more common language of course the terms will change their meaning. Just as “literally” now often means “figuratively” I’m not going to die on this hill. But I will try to resist degradation of terms that have specific technical meaning.

So I would very much disagree with the statement that memory safety and sandboxing are orthogonal. They are certainly different. Linearly independent even. But with a fair amount of overlap.
