imo, in most cases you don't really need it anymore, it clearly work well for you, of course i still recommend to learn the skill if you have time
as for the future development case, we don't really know what will happen, even until today agents still hallucinate and struggle to remember the context in the long form
atleast for me, i don't trust ai / agents 100% to completely detached myself on development, especially on reviewing and verifying part, they can cause more damage and time if something goes wrong, which almost certainly will, given some time
