In the quantum world - at least as we understand it today - nothing is really distinct. Throw a couple of quantum things in a bowl (particles, cats.. etc.) and they will start mixing in combinations that seem perplexing at best, or down right absurd. In the same way, our measurement instruments form such a "quantum salad" with the very thing we want to observe.
This notion has a lot of consequences and I find it exciting! For example, we can harness it to shape and engineer what's "left" of the system we are interested in after we measure just some part of it. "Reading" quantum information while trying to "write" another and vise-versa are inevitable processes in the quantum reality. These ideas can be used to enhance the way we observe the world (microscopes for example), as well as the way perform computations (quantum computing & purpose machines)!
With better senses - such as "eyes" and "brains" - these revolutionising concepts can carry us to our next chapter.
