I've been at the same company for 20 years, and when I read an article like this, I have to wonder if I've done my career harm. I've held many different positions at this company, and have survived the dot-com era and the recession. I'm more or less satisfied with the pay, but always have that nagging question if the grass is actually greener on the other side. All that may be moot, I'm now over the "tech Logan's Run" age of 40; will a recruiter simply assume I'm a dinosaur that hasn't learned anything in the past 20 years of delivering software and services?
