I think that QM, as a framework is well understood and nearly complete.
There is surely much more to invent, but if we were given some future
technology, and a schematic of its construction, I think there's a good
chance we could explain and understand it's function with our current
knowledge of physics.

Of course, there might be some unknown force or family of particles we're
still unaware of, but given the energies probed so far via particle
accelerators, we should have seen these other particles or families of
particles by now, unless they only exist at incredible extremes of energy
and temperature.

Where our understanding is known to be limited limited relates to edge
conditions, at very tiny or scales, where gravity becomes as strong as the
other forces as in black holes, and in cosmic scales, such as the nature of
dark matter and dark energy.

Sean Carroll summarizes this point here:

He says what we are confident we understand well are the physical laws
underlying everyday life.
