SO how long is it before some really enthusiastic hacker creates a 3D emulator using a graphics engine like that in DOOM, that allows you to pop open the cover and go INSIDE the machine, home in on specific ICs, resistors, capacitors, etc. and stick a probe or voltmeter up to the leads? Basically, it would incorporate a CAD system with a SPICE system. You could then get really agressive and add a toolbar that has a probe, voltmeter, soldering iron, solder, and a whole warehouse of parts (74xx series TTL, resistors, caps, transformers, transistors, etc) so you can make hardware mods to the system. Later on, when they invent the Scent Printer (a device which emits the smells of the computer you are working on) you'll be able to know when you've shorted something because all of a sudden a foul, toxic cloud will be emitted.
