I'm pretty sure Google is already using plenty of "AI" behind these functionalities. Heck, image classification was the very beginning of the current "AI summer" a dozen years ago! Not nearly everything in AI is ChatGPT, not quite all is NLP for that matter, there's still plenty of interesting things which are improving. Dropbox might well be pivoting to improve their e.g. photo/video offering with AI, but they might as well have started that 5 years ago.
