Quantum mechanics (physics) makes lots of testable predictions and has many real world applications. Starting with black body radiation: https://en.m.wikipedia.org/wiki/Ultraviolet_catastrophe Double slit experiment, Solid state physics, semiconductors.

Mathematical models are not bs.

I think you will need some bs to be successful at sales, but I wouldn't try to use quantum mechanics in sales.

You can talk about GTR to someone without the use of mathematics and explain to them that time moves differently at different speeds, and that gravity effects time.

You cannot do that with quantum mechanics without bringing in a "probability wave", or a hypothesis that "maybe energy levels of systems are discrete", which anyone would agree doesn't make any sense by itself.

That's a really poor argument.

You can't demand that the universe works in easily comprehensible ways and discard a theory on how easy it is to explain without using math.

If you wanted to talk to someone about Quantum Mechanics you can start with black body radiation, the photoelectric effect and wave particle duality and the experiments that lead to these discoveries.

Then let's move on to precision tests of quantum electrodynamics done with low-energy atomic physics experiments, high-energy collider experiments, and condensed matter systems leading to the empirical evidence.

To me saying Quantum Mechanics could be BS is like someone saying evolution is BS because, well it's just a theory. Let's ignore all the facts that have been repeatedly confirmed through observation and experiment and pretend that "scientific theory" means the same thing as saying "it's just a theory".
