A philosopher argued at least one of three unlikely things about reality must be true

In 2003, philosopher Nick Bostrom argued at least one of three propositions must be true: almost all civilizations go extinct before they can simulate conscious minds; those that survive choose not to run such simulations; or, if any civilization does run them, simulated minds would vastly outnumber 'real' ones, making it overwhelmingly likely any given observer, including you, is simulated. Bostrom wasn't claiming we are simulated, only that one of the three options must hold.
