I think it's basically the bottom two of your options.
Extensive experience (beyond say 5-10 years) isn't valued for ICs. There's so much churn in tech stacks, frameworks, etc that anything anyone was doing 15 or 20 years ago is now totally irrelevant.
This leads to burnout from lack of progression, and either people go into management or they drop out into something else.
