Personally, I find AI/LLM agents to be very useful in software development, dramatically improving the current imperfect practice of the art to something - not perfect - but quite a bit better than was practical / possible even one year ago.

The MD I worked for spent six weeks researching problems a friend of his had before the friend died, if he could have done that same research in a day instead of six weeks, he (or any other M.D. doing the research) could have saved his friends life.
