If you were a developer affected by stuff in the '00s, you're probably nearing the end of your career (unless you'd just started) The problem here is the lack of a NEW talent pool.
Is 47 really "near the end of your career"?
I always get a chuckle when some hopeful naif writes like they're going to retire at 50 and be done. Most everyone I know who's tried that "gets bored" and goes back to work or starts consulting after a half year trying to find their feet. Those are also the ones who when asked what happened tell you they've got plenty of good years left and are now planning on retiring at 70.
47 is still building steam in my experience.
As a non-lead, non-management code slinger? It's usually well past it.
