"basically An Occurrence at Owl Creek Bridge" is a perennial category of fan theory, along with "they were dead/in purgatory/hallucinating in an asylum all along" and "$X is a Time Lord." The latter i've also seen about James Bond.
And of course Nikola Tesla. Which probably makes Edison The Master. There's definitely an AU fan fiction in there somewhere, which in its Golden Age (electropunk?) Lovecraft-noir incorporates "Edison's Conquest of Mars[0]," an influential but otherwise garbage sequel to H.G. Wells' War of the Worlds. Sorry, what was I.. oh yeah. Tunguska. Obviously Tesla accidentally reversed the polarity of the neutron flow.
