I like how they toss around the term "microchip". I've not see a macrochip, at least not yet. Maybe it's macro if it gets over 4mm on a side? That would be pretty big.
Anyhow. IC's tend to be rather specialized, and not all that interchangeable. Getting a batch of them isn't saying much: a car no doubt has microprocessors of several flavors, RAM, ROM, amplifiers, voltage regulators, voltage convertors, CAN transceivers, and a whole host of different microchips. Leave out one and it's not going to work. Saying GM got a batch of microchips is like saying they got truckload of bolts.
