It's like cars. I have a faint idea of how an internal combustion engine works, but I want to be able to just turn a key and drive. I don't need to know about the innards under the hood. If something goes wrong, I get someone to fix it.
Same with the TV. I want to turn it on, and hopefully have a remote control that doesn't have more teeny tiny buttons than the space shuttle. Those of us over the age of 30 remember when our TVs got three or four channels. Now we're expected to know what S-cables and routers are, and what is compatible with HDTVs and what isn't. I think I'll read a book and use my TV for DVDs.
