Will quantum mechanics play a key role in engineering in general in the future

This maybe a really crazy question, but with the discovery of coming pretty close to creating a unified theory combining quantum and real world physics by modern physicists, do you any of you think this discovery can have real world applications in the engineering fields in general in the future?

The reason I'm curious about anybody's opinions is because the youtube video I have seen of a motionless electromagnetic motor that pretty much runs on free energy if any of you can watch the video in this link...

I believe that quantum physics plays a big part in how this motor operates despite it defying the 1st Law of Thermodynamics. And I believe quantum physics may have many applications even in civil engineering and environmental engineering since I now have the idea of including how quantum physics may play a key role in environmental engineering applications for my master's degree thesis.

I would like to hear your thoughts about this from anybody, even professionals in related fields and grad students. Thanks.

Quantum will definitely play a role, although quantum is really only relevant in very small phenomenon. Everything can be treated as continuous when things become large because the jumps are so small. Even when/if quantum, relativity, and everything else becomes unified, there are still many easier ways to explain macro phenomenon. Think about gravity, it is currently being explained by nuclear physics and virtual particles and such, but why would somebody do all that when they take gravity into account?? They can simply use the earth's or other body's gravitational constant and treat it as a macro phenomenon. The math and theory become much simpler that way, even though it is cool to understand the quantum relation of gravity and virtual particles.
Personally I think quantum will become increasingly relevant in nanostructures, material science (which could produce civil materials), semiconductors, magnetic devices, optics, computers, and many new technologies that rely on small/nuclear/photonic things. I do not think, in any way, that it will become something that a civil or other macro engineer will care about. Science is full of surprises though. These are only opinions.
