Is "Everything is Real" a reference to qntm.org/ra , a phrase that you and that both got it from, or something that you just independently came up with and capitalized? Also, can you clarify what you mean by "wasn't serious anyway"? Note: I do not think that there is a significant chance of roko's basilisk occurring. (where significant means "neccesary to consider when making decisions")
