I'm not sure how you assume chaos theory creates big issues with determinism and with what you wrote. I wouldn't agree with someone how an impossibility, "for beings inside a system of predicting how the full system will function" as conflicting with determinism. Even when a deterministic system is influenced by an outside deterministic system holding variables hidden to the initial system. I wouldn't described as undetermined by human language and write off determinism. I would say it's personal perception and arguable. Similarly I don't believe a defeatist mentality should be adopted with understanding chaos theory towards determinism. To me that would be taking an early stance, limited by our current knowledge and tools. Absolute impossible seems arrogant.

There is nothing defeatist about it. It's about finding the nature of the universe. I don't know why if a certain model of the universe would show up as being less accurate than another model - anyone would that "defeatist". I think it is important as scientist to not lock oneself to a specific model and think that it is defeatist if that one model shows up to be incorrect.

Well I wouldn't say a deterministic model has been shown to be incorrect. It may come down to what is most measurable and what we decide to lean towards but I think it's way too early for that judgement. I would find it interesting if one day I go around without a determinism perception towards everything. I just haven't been able to do it with what I've read and thought about. I don't think I'm stubborn either!
