People with genuine talent in the industry have extremely little to worry about, IMO. I was shopping for a used car shortly after the 2000 crash. Car salesman found out what I do for a living and said, "Yeah, I was a programmer for a couple years; made a lot of money. Then when I got fired and couldn't get another job, I went back to selling used cars."

The no-talent temporary programmers are the ones who flood into and wash out of the market in crashes. If you have genuine talent, your time between employment is measured in hours right now, in days during normal times, and maybe in weeks during crashes.
