I said we couldn't see quantum phenomena, not that we couldn't indirectly observe them.
The uncertainty principle relates to the nature of quantum "particles", in that you can only detect any properties by interacting with them, and any interaction changes their properties.
You talk about "tracking" electrons. That's analogous thinking. I. E. That implies that they are things that move around spacetime in ways that are like the way things move around at a macroscopic level. But they don't. An electron isn't anywhere until it interacts with other particles. It is one place, then another and between those places its path is probalistic not real in our space. That doesn't make intuitive sense, because our brains can't really cope with quantum mechanics.
