Sure, but this is mostly irrelevant because software dev is one of the youngest fields. Something like 70% of professional devs are under 35 depending on which survey you look at. And the number of CS graduates exploded over the last decade.

The only reason the numbers aren’t even more tilted is because people stopped hiring juniors 2 years ago. But they’re out there, and if there’s a new technology around that makes them vastly more productive than the seniors today, there’s nothing stopping companies from hiring them.
