We are not alone.
I live to love and serve.
I didn't do the math; I'll show my work to you anyway.

Contextuality is a topic that bridges physics, mathematics, epistemology, and ontology, and to me, it makes sense of Vedic spiritualities in a rigorous, satisfying way. True Woo.

I'll conclude with what I said at the beginning. We know the K-S theorem intimately: it comes up in any choice that turns an ambiguous situation into a defined one. We choose to be present realities which are self-consistent away from others.

What do we have left? To understand how it is we can have a shared reality in the first place, with shared laws of physics and overlapping experiences in time: puzzles I will bring up another day.

In the end, because we can only pick two of three conditions—VR, VD, and NC—we have three worlds to pick from. But two of these worlds defeat QM. We accept that the physical world is, relational, participatory, and perspectival, with no "view from nowhere" that encapsulates everything at once.

Quantum mechanics forces an impossible choice. Bell's theorem shows we can't have VR + VD + locality. Kochen-Specker goes further: we can't even have VR + VD + NC. Even without spatial separation, even for a single particle, we must give something up.

But with quantum mechanics, K-S shows that this can't hold for our random measurements. There is no pre-existing assignment of values—no hidden spreadsheet of "what each observable would be if measured"—that could reproduce quantum predictions. The measurement context itself matters irreducibly.

For anyone with a statistician in them, there should be nausea. Given a random distribution of data, methods such as PCAs or HMMs unpack variance into factors that could, in principle, replicate the dataset in some limit.

So much the better. Kochen-Specker does something even
stronger. It rules out the idea that variability and randomness implied by the Born Rule can be explained by unknown variables whose values we haven't observed—even without invoking spatial separation.

Or we accept spooky action at a distance.

Let's talk about Bell Inequalities first. Bell Inequalities tell us what it means for a quantum system to exhibit non-locality. They show that quantum correlations between spatially separated measurements can't be explained by local hidden variables.

There are good reasons to care about this if you are into making quantum computers fast. It turns out that exhibiting contextuality is something that many quantum algorithms have in common.

What is this key element? "Contextuality". In jargon: you cannot presume a global set of value assignments exist to variables with quantum measurements.

Not streamlining metabolism: VUCA should be catabolized into signal. This moves resilience to antifragility.
