The problem with current theories is that I understand them when I reading them. It's like piece of complex code or book with complex but boring text, like phonebook. I can follow it, when I read it, but I cannot reproduce it when book is closed.
Can we teach a phonebook to kids? Yep. Is it useful? Nope.
Recently, I did "quantum physics in one picture" experiment. Results are very good: lots of reposts, comments, interest in topic.
In short, pilot waves were a worthwhile avenue of research, but we have seen they are incredibly cumbersome or even insufficient in many quantum mechanics problems.
Entanglement is hard problem for PWT. Photos of entangled photons[0] are intriguing, because they look similar to behavior of walking droplets in some experiments (see dotwave.org feed). I hope, someone will be able to reproduce entanglement in macro. Currently, my top priority is to reproduce Stern–Gerlach experiment in macro (I suspect that interference between external field and particle wave creates channel, which guides particle into spot, but it better to see it once). Second priority is creation of "photons" in macro. Entanglement will be third. IMHO, all of them require microgravity to reproduce in 3D.

A kind of Pilot Wave can explain quantum weirdness to layman people with ease.
We can ditch theory relativity and calculate speeds relatively to CMB, which is much easier to understand.
We can ditch Big Bang theory and, instead, accept that light is not immortal, because it ages with time. IMHO, Dipole Repeller and Shapley Attractor are much more attractive and easier to explain than Big Bang.
