n=small, but I've had multiple friends who did freelance technical writing and copyediting work tell me that the market died when genAI became easily available. Repeat clients no longer interested in their work, and all the new work postings not even really worth the cost even if you tried just handing back unmodified genAI output instantly.

So I find this result improbable, at best, given that I personally know several people who had to scramble to find new ways of earning money when their opportunities dried up with very little warning.
