In the "….Of Great Mathematicians...." blog I discussed Einstein and current researchers' difficulties in creating an appropriate Mathematical Framework. I'd like to add to that.
Albert Einstein was not a mathematician. In his scientific biography, “Subtle is the Lord”, his friend and colleague Abraham Pais identifies, especially in his Appendix, over thirty mathematicians with whom Albert collaborated: in his quest to interpret Physical Reality.

They shall quickly get over it and find new markets elsewhere if the worst comes to the worst. Alas is a Huawei component still to unfold, caveat emptor?
