Abstract. The quest for future deep foundations of physics should continue to pursue greater unifications, should incorporate “hypercomplex numbers” or the name “Clifford algebras” in describing its quantum realm; develop a language for discussing in what way “quantum-waves” could be considered “real;” and should always be capable of expressing the formulation and interpretation of any fundamental theory so that humans might believe it is isomorphic to Nature’s actual mechanisms. That is not yet the case for present-day quantum mechanics nor quantum field theory. In addition, there is probably a limit to testably-assured knowledge perhaps three to six orders of magnitude in particle energy above present capabilities. If “ultimate reality” lies beyond that, we will never have confidence in identifying it.
