What does the closing of CompUSA have to do with computer science? Absolutely nothing, and yet everything. Computers have gone past devices you had to understand, ripping them open to add memory and other components. Now they get sold as a commodity not much different than televisions.
We do still have computer stores nearby. The local mall has an Apple Store and a Dell kiosk. But these are just showrooms, ways to exhibit their products, not places to go to get nuts and bolts to keep the computers going.
A field "Television Science" would never have flourished, but unfortunately many young people view Computer Science in a similar way today. That does not bode well for the long-term future of our discipline.
