This is going to be a controversial opinion. The quality of your average tech worker has completely nosedived in the last 10-15 years. All these huge companies wanted more products, more marketshare, more money, etc. They needed more people to pull this off. They started lowering hiring standards across the board because there just weren't enough people in tech. Simultaneously, a huge portion of the world saw tech sa…
What I suspect is that tech companies have many more workers than needed, because most software simply doesn’t need many people to build and maintain. I remember massive tech companies running on teams of Google search, Github, AWS, Outlook, Facebook, Uber, IntelliJ. These are software behemoths, but at their core they’re rather simple, and a single developer could make an MVP of any in a few weeks, and with adequate testers and resources, something scalable and stable that could be used by professionals in a few months. And that’s creating it from scratch (well, existing libraries), though maintaining everything maybe doesn’t require much less, it surely doesn’t require more. I understand the big products have more, at least name recognition, and I understand that a big product needs more than programmers (asset creation, marketing, QA, tech support, accounting, etc.) But the software development side isn’t very big, especially if you already have the software.
