In the years immediately following the dot-com meltdown, there was more tech labor than there were tech jobs. That didn’t last long. By 2005, the tech economy had bounced back on its own. After that, the emergence of mobile (a new and lucrative category of tech) plus low interest rate policy by central banks fueled demand for tech. Before the first decade of the century was out, “tech labor scarcity” became an accepted norm.
The tech labor market heated up even more over the course of the second decade of the century. Rising equity valuations armed tech companies with a currency more valuable than cash, a currency those companies could use to secure labor through things like aggressive equity bonuses or acqui-hires. COVID distorted this overheated tech labor market even further, as low interest rates for longer, a massive fiscal expansion, and even more business dependency on tech spurred demand. Growth was afoot, and this once-in-a-lifetime growth opportunity wasn’t going to be won with bog standard ways of working: it was going to be won with creativity, imagination and exploration. The tech labor pool expanded as tech firms actively recruited from outside of tech.
The point of this brief history of the tech labor market in the 21st century is to point out that it went from cold to overheated over the span of many years. Not suddenly, and not in fits and starts. And yes, there were a few setbacks (banks pulled back in the wake of the 2008 financial crisis), but in macro terms the setbacks were short lived. It was a gradual, long-lived, one-way progression from cold to super hot.
