The wave function collapse is believed happen based on *anything* "knowing of it", not just a human.

Yes.
The determinism camp, and the probability (free will) camp.
Believers of determinism like Albert Einstein were winning, and now the free-will believers cite quantum mechanics as evidence that matter functions based on indeterministic probability, not determinism.
At first QM seems like mysticism, however, fundamentally, all that happening is
random particle collisions, and consequently indeterministic positions/momentum/energy imparted to these particles based on these collisions (exemplified by the Heisenberg Uncertainty Principal of Momentum and Heisenberg Uncertainty Principal of Energy) .
The free will believers say that since human thought is
particle matter, then it follows the above mentioned
indeterministic probability. Therefore, humans have free will.
The believers of determinism counter-argue that QM only seems probabilistic, because we just don't understand the greater deterministic math of the universe.
