"No, if you want "why" or "truth" look into the philosophy department."
Thats a bit defeatist. Science has always been about explaining the "why". Why is the sky blue, why do the planets going around the sun etc.
"Quantum mechanics describes a fucking ton of things"
It doesn't really explain anything. Its a convenient probabilistic bucket to put stuff in that we don't really understand but like to give it a name anyway.
"What" is for engineers. Physicists should always be aiming to answer the "why". Anyone can use equations, explaining why they work and where they come from is should be theoretical physics main goal, even if ultimately there's a level of reality we can't understand or progress beyond. No hand waving philosphers should be required.
