Linking it back up to my original question ("what happens if you don't press the button?") - I suspect Google cannot actually know you weren't going to. The outcome is computable but intractable.

Free will is just a level of analysis that assumes the outcome is intractable, and doesn't bother trying to compute it.

I don't know physics, but can't quantum phenomena be deterministic? Maybe we just haven't discovered the rules yet.

Well, if everything is deterministic we might as well scroll to the end.

I think I’ll go with random quantum please.

How's that any better? You might as well scroll to the end there too.
