If k was a vector valued function dependent on position and time, can this model any wave?

Debatable, there is a limit to how much scientific knowledge can improve one's health and living conditions. Not everybody needs to know how to solve schro's equation but everyone should know to not mix amonia and bleach.

Dude how, nothing on quantum, a bible... this doesn’t seem based at all. It’s diverse but some of these are just introductory books, like that physics book.

I don't know what you refer to, but this ansatz does result in plane waves.
k * r is also a valid solution.
