The first careers I witnessed being negatively impacted by AI coming onto the scene .. just a couple years ago .. was tech writers. Source: my personal network of tech writer colleagues.
tech writers disrupted by AI a couple of years ago? Seems very dubious. A couple of years ago, AI was terrible at writing anything.

Either your colleagues are facing stiffer competition off-shore (not LLM driven) or their jobs were more about organizing, checking and sorting topics and data (LLMs can take that away)
Have seen the same thing happen to literary translator friends. Barring the very rare few who broke through to international fame via well-known literary award, the rest were largely sustaining themselves with more mundane business translations and that work is ended.
