Free will

 If the future is set then why should we bother?

• There is a difference between known the future (as commonly is thought be the case) - and there is only possibility of you reaching to that predetermined future. Determinism is saying our future is deterministically will reach to a predestined future.
  
• Determinism vs Fatalism: Determinism is not Fatalism. Fatalism says whatever happens will happen. Fatalism is passively waiting for the outcome in the future.
  
• Determinism means your action matters to determine your future.
• Your decision making process is computation based on decades of inputs. Your action and volition -- power of using your own will -- is a result of all those inputs plus the input you are currently receiving. It is extraordinarily complicated algorithm which works on these complicated input for you. You are receiving this unique input. None has these inputs.
• Partial Knowledge of Future: Ted Chiang argues that although we don't the exact future but we know part of it for sure. For example, we know we will die, we will suffer some losses, we will have some joys, etc. Animals or AIs don't have this future knowledge.
