I think that's already true today. The problem is, when theorists are out manufacturing new theories, I think it gets very confusing/handwavy (because everybody is brought up on handwavy fundamentals).

There are no "handwavy" fundamentals. The theory is well-studied, well-understood, sound, and produces verifiable results. It is, however, incomplete, in that it does not provide an explanation for certain phenomena.
