It's happening - AI is definitely kicking this self-employed copywriter to the curb.
My wife (63) retired last year, and she loves it. I still have a few steady clients that I hope to keep, but my workload and income have been cut by about 60% this year. I'm 59 and have zero interest in reinventing myself, getting any kind of job, or putting my nose to the grindstone to get more work. I had a nice 20+ year career doing this, and I'm ready to take it easier. So basically I'm semi-retired right now. I take every friday off, and my 4-day work week has about 10-15 hours of "do them whenever I want" tasks.
No pensions here - just SS. But we don't have kids, have saved/invested quite well, and live a fairly simple life with zero debt besides a cheap covid-mortgage I'm in no hurry to pay off. For health, even if the premiums go up, hopefully the ACA we've been using will still be there until Medicare.
Unless I magically get more clients (a slight possibility - I have a column on Inc. so I am always "out there"), we'll be making some changes next year. The first one will be me, with my new-found time, taking over the lawn work from the (somewhat expensive) services we use. I'm super excited - finally getting the tractor I envisioned when we moved here four years ago!
