Beamforming with a phased array is talked about in the article, but you are conflating two very different types of arrays. You can't form beams with the types of macroscopic arrays I was referring to, since they consist of macroscopic array elements whose phase cannot be controlled, and reside behind a fixed lens that ensures that they all point in different directions.
Ok, but now the software can cause the failure. Not sure if that's much of a relief.
