As someone that works in tech, it should be noted that many of those laid off were probably able to find work elsewhere. It’s a shitty market for tech right now, but there are jobs out there.
The industry that is really struggling is recruitment. Many people that I spoke to that were laid off from Amazon are still struggling to find work a year after losing their jobs. If you build a career around hiring in tech, and the industry goes into layoff-mode for 16 months, there’s not much demand for your skills.
