but using it as a tool as a professional can very much improve your work and how quickly you do things.

Maybe it's just my 20 yoe, but that has so far not been my experience with it. It is improving, but definitely not there yet. Even standard boiler plate I can typically bang out faster than asking the AI to do it and then needing to double check it's work because it somehow still manages to screw that up occasionally. Sometimes it does manage to be better than one of the juniors, but using it that way also cuts the legs out from under the career development pipeline which will result in an intermediate and senior dev drought down the road.
