I will always have been back. The precise nature of time travel in the Terminator universe has been the subject of griping from philosophy-trained bloggers and whole anthologies by academic philosophers. Despite valiant attempts, including this thorough assessment from M.

Something about them inspires infinite possibilities. Am I not alone?
