Yeah, I was reading a reply where some guy said he could be a turing machine if he had enough spare sheets of paper to work with and that's not how human working memory works. If we assume that a cow is a spherical object in a vacuum then sure, buddy, you can simlulate a turing machine. But in the real world your meatsack can only manage so much stuff in your head and eventually you'd reach a point where you would no longer be able to keep performing the tasks necessary to do your turning machine thing. that's one of the most important things computers have going - You can store shitloads of information in memory and hard storage without losing track of it
