Yes, replacing Googling is a huge speedup. Let's say I want to know how to make a certain badly documented third party API dance the way I want it to. In the past you had to piece the picture together from forums or tangentially related stackoverflow posts. You can now ask the AI directly and it'll respond with the pieced-together answer. Caveat is that the answer can be hallucination and that seems to happen somewhat regularly. Trying it and checking that it is indeed doing what you want is still necessary, but the time-wasting hunt for information has been cut down.
