If I understand yc-kjh's point, their "semantics" are really just more complicated syntactic rules. No real understanding occurs within the code. Or, the code doesn't understand what it's doing it's just doing what it's been instructed to do by us. (On that note, the code doesn't understand anything because the code is a non-entity, it's a thing, like a book or a car engine. A car engine doesn't understand the fuel it's burning or the gears it's turning or why, it just does it because that's what it does.)
