Truth. It poses the same question. And therein lies my answer, I would take the red pill if it afforded me a way to return and help others find 'reality'. Much like a true philosopher after leaving, who returns to the cave to help those still inside.
What I am trying to get at, is the can of worms that this question proposes. Are somethings real (ex: my mind) and some false (ex: my simulated body)? Are there 'others' to show the light outside the cave?
