Then factor in all of the new things they get to design - Computers, laptops, tablets, mp3 players, video servers, wireless devices and routers, and everything else. The amount of items they design now has increased ten fold. Not to mention cell phones and all of the devices they use.

We still listen to music. The devices we use to listen to music have changed. They don't design huge stereo systems, instead they design smaller mp3 players and wireless speakers.

In this case, the social implications are just the opposite. They still design stereos. But the field has expanded so they design and manufacture so much more.
