The bad news...
I currently do, all by myself, the kind of work from my garage that, twenty years ago, would have taken a few draftsmen, an artist, a typesetting house, a print shop, and a number of other things.
While this is great for productivity, I can't help but wonder if this isn't making a dent in employment somehow. On the other hand, so many new types of jobs have been created by the computer industry (many major industries today didn't even exist in 1970) that it's probably at least a wash.
