I'm not sure whether to feel vindicated to see someone else echoing my own internal thoughts, or to feel nauseous about reliving those years. I was fortunate enough to have been at a company that was making money, but I still remember growing from 500 employees to 4000 or so in 2 years...and then dropping back down to 1500 two years later. We bought a small software company for the talent, and 3 months later was told to layoff the entire team.

Many great colleagues left tech at that point to become Realtors, landscapers, accountants. This is not to say that we are destined to relive exactly the same fate, but it's good to remember that rapid change is always a possibility.
