Great points, and I fully agree, but I want to go a bit further.
General Relativity is amazing and wonderful, but I think we can safely say it's not complete or fundamental. Aside from dark matter, the insides of black holes, and quantum effects, it doesn't provide any mechanism for curved spacetime. As much praise as I think Einstein and GR deserve, too often I see and hear people treat it as the ultimate truth of the universe, particularly curved spacetime. I'm somewhat skeptical of String Theory, but I expect some of the mathematics will prove useful in whatever theory emerges successful over the next 30 years or so. For instance, something akin to superfluid vacuum theory, with spinning toroidal vortices as fermions, might well have properties similar to strings.
I am encouraged by the return of aether in several theories, which shows that the community is slowly getting past the misconception that aether was disproven and discredited when it fact it was one very specific aether theory that was shown to be inconsistent with the evidence. It is challenging, especially for a lay person, so stay on top of all of the theories and experiments, what was disproven, and what alternative theories are actually promising versus those that are silly (particularly when discussed on internet forums). However, we must avoid getting too stuck in one particular paradigm, otherwise it will take that much longer to discover the more fundamental layer of reality that underlies the physics of today.
