In a sense, every aspect of the universe really is truly profound, and any small humanly observable part recapitulates the principles sufficient to derive larger scale behavior, if we have faith in science anyway. Really paying attention to
anything is a valuable learning experience.
Education helps develop the language necessary to explicate such profundity. E.g. the behavior of coupling between different "forms" of energy at the same energy level suggests that it really is all vibrations, in one completely valid and predictive model of the universe.
A person describing something they lack the language to describe does sound stupid, as you might notice when someone ignorant talks about a field of your specialty. Or when a child talks about adult social interactions which they observe.
If I did not have a doctorate in chemistry, I might totally dismiss some stinky longhair ranting about coupled vibrations. But I do, so hearing this I am more likely to participate in a dialog, help anchor the metaphor in the physically observable, and maybe even learn something unexpected.
In my personal opinion, a little belief in profundity leads people take better care of their environment (including social), pay a little more attention to the world immediately around them, and find a little more existential meaning in the everyday quality of things.
Of course, people do go crazy and ignoring that isn't helpful. But the real harm is in action, not in belief. Some religious people feel compelled to do charity work. Some religious people fight wars. Some religious people stand on the sidewalk and preach in rags. The first case is objectively good, and the third case is mostly harmless.
Instead of framing profundity as an inherently problematic sense, maybe we could frame it in terms of getting trapped in local minima and of acting inappropriately. If someone believes they are Jesus Christ reborn, for example, maybe everyone else is also Jesus Christ reborn and nobody needs to make a big deal about it!
