@dalias Yeah, the "question" of free will only remains a question if you are a dualist or whatever. For a materialist like myself, who believes that the mind is what the brain does and is fundamentally just a physical system like any other, quantum mechanics is pretty clear about how there is always at least a small degree of uncertainty involved. And even if you ignore quantum effects, a perfectly deterministic chaotic system (eg, the weather) is fundamentally unpredictable too.
