Its not the end of your dreams, just different. Mobile apps stores are the exact same marketplace and business trajectory as cdrom multimedia in the early/mid 90s. I'm sure they'll be another, probably unpredictable tech driven bubble in the future. The endless wheel of IT keeps on turning and something else will rotate up soon enough.
"I can't imagine that there wasn't enough good work out there"
Toward the end of a bubble the work goes away no matter how good you are. As far as I know he was pretty good. Which has pretty dire implications for the rest of the marketplace. The worlds best finish carpenter got fired in 2007. The worlds best multimedia cdrom designer got fired around 1996ish. The world best atari 2600 programmer got fired in 1983ish. Its the bubble that caused the problem, not the man.
