I'm just as "old" as you with one exception: I keep learning as much as I can every week, including bleeding edge tech. Even with this market things are kind to me. Do the same. Learn outside of Cobol. Take a look at what tech, like ML, is still in high demand and drink from a firehouse. Just because you are experienced doesn't mean you are obsolete, but you need to work on improving yourself and adapting to the new reality. If I can do it, you can too.
