I'm not sure I follow.

If determinism is correct, then given enough storage and computational power (or intelligence capable of doing this within their mind), an outside observer would be able to figure out every single action I would ever take before I took it.

If how my brain works is deterministic, and all of my encounters are able to be pre-determined, and those all deterministically shape my decisions and actions, then... how I can I possess libertarian free will?
