When did the world become 'outside' though?

Computing is irrelevant to us without i/o, so why should we expect that it is any more relevant to itself?

Obviously computer science does not consider i/o to be ontologically necessary, but I am proposing that is because computer science is theoretical and exists within a toy model of itself, rather than a thorough account of what is ontologically required realistically for computation to arise. >>> I was just answering your question honestly and as accurately as I >>> could.
