so how could you know it's real or it's just signal?
so <>'s logic is correct and you cannot prove it's wrong, unless you can prove two person's singal coming from you two interaction is in fact independent and senses that from interaction of you two can only happen when you two are really interacting in a real world. Then the virutal " singal theory " is proved to be untrue because it would then impossible to have common singals in your two's interaction because signals from individuals shall be theoretically independent and thus unable to make it believing that virtual interaction could generate common senses.
