No one would ever call me a 10x engineer and I am in your same age group, yet I find that there are plenty of jobs out there for me (or at least there were pre-pandemic). What could explain why I can get interviews and job offers and you cannot? Because it's not age. Maybe stack? I'm all JavaScript. Maybe region? I work remotely (out of state) now but most of my ~5 year career has been in the Bay Area.
