Nothing has changed, though. In my office the ones that have really boosted productivity are the ones putting in the effort to craft solid prompts and understand when to move that slider on reasoning effort and model selection. Or understand and put thought into how to leverage the tool, like project folders with the context to all or part of your job the model can reference. Everyone else throws a lazy prompt at the default 'instant' model, gets a crap response and then they give up.
