Thanks for an interesting read!

I don't buy the whole "quantum effects can only exist on atomic scales" argument. To begin with, experiments have steadily been demonstrating quantum effects on ever larger scales (quantum teleportation, quantum encryption etc). Second, and more important, if there was a break in scale between the classical and quantum worlds there would need to be some sort of threshold. Where would that threshold be? It feels very arbitrary. I instead subscribe to Everett's interpretation of QM: https://www-tc.pbs.org/wgbh/nova/manyworlds/pdf/dissertation.pdf (well worth a read) in which the alternate possibilities of the wavefunction all happen but at different points of the Hilbert space. The uncertainty is not about what happens but about where in the wavefunction we live. When we observe quantum behavior it's because we make a measurement and become entangled with the system we measure, when we observe classical behavior it is because the interaction between the system and its environment causes decoherence between us and the system.

I'm starting out with Steemit myself by the way, I just wrote my first post on building a system of ethics from first principles as a complex adaptive system: https://steemit.com/ethics/@raztard/ethics-is-an-optimization-problem
Maybe you'll find it interesting?
