We are only just starting to experiment with quantum systems and I have hope that there are still many things we can discover. Our understanding of light alone is kind of brain breaking in some ways. It acts like a particle and a wave, but it always has a wavelength even as a single photon. And a photon is more of a quantized description of a certain amount of light energy than an actual particle with mass, as I understand it. It all stems from a certain fluctuation in a specific quantum field, so we may be able to discover properties which allow us to manipulate these as well as other quantum fields. For me it kind of boils down to the more we understand reality, the more complex it becomes, and it always has more layers. We don't truly understand what reality even is, and can only experience certain parts of it with our senses. So have no fear, the drive to understand what is going on around us is a very human trait and we have built some of the best tools in the history of humanity in only the last 60 years. There's a lot of runway left on science :)
