A reference to the many layers of abstraction, emulation and virtualisation now present in modern computers, so much so that the latest generation of computer science students have no idea how computers really work. This hiding of the inner workings of computers has been done so students can work with high level languages and abstractions to deliver significantly more function points of software behaviour with very little effort.
Professor at an IEEE conference on Software Engineering leans over to his colleague and says "I hear the latest round of students are so bad they barely understand what a virtual machine is" colleague: "Yeah, if we keep this up they will all soon be in The Matrix". Nearby student overhearing says "Professor, what do you mean?" Professor: "shut-up and get back in your virtual", then colleague whispers: "I bet he doesn'teven realise his i7 chip has hidden 128-bit registers". Now grumpy professor to student: "You are all in a virtual!"
