> This is a misconception that's often repeated I don’t see how “If you use Chebyshev points, polynomial interpolation isn’t problematic” is a refutation of the claim “Polynomial interpolation between a given set of points can be problematic”. That given set isn’t necessarily, and typically isn’t, a set of Chebyshev points. That’s like saying “Integer factorization isn’t hard. If you pick powers of ten, it’s easy”.
