I agree that the problem is materials science. My point is how much money is actually being allocated towards that vs sending stuff in space, to what end? I don’t follow material science stuff super closely but as far as I’m aware the investment is orders of magnitude less than propulsion and other tech. Then again these things just take time unfortunately
