AI powered tooling is amazing. I already use it regularly for my work (I'm a programmer). It's primarily in the form of intelligent auto complete (lookup GitHub copilot for an example). But AI can also do stuff like catch some bugs, automatically address code review comments, etc. I look forward to seeing it being able to generate larger blocks accurately (in particular, I'd love it to automate test generation -- it currently can only handle very basic cases).

I'm sure other industries can benefit similarly. Eg,

• Video game level design could take in some assets you made in the theme of what you want and then generate slight variations. We've already had procedural generation of stuff like plants for ages (you can generate countless slightly different tree models, for example). This is just the next step into more complicated structures. For example, suppose you're making a huge office space, like in Control. Many desks and whiteboards in that game suffer from asset reuse. AI could help give slight variations to make the setting feel more natural.
• Graphics designers I'm sure already benefit from "magic eraser" functionality. It used to be time consuming to remove something from an image. Now it's easy. I'm sure the next step is generally easier image editing, like moving objects in an image (Google demoed something like that at I/O).
• Countless scientific uses, especially for chemistry and biology, because AI can be really great at constraint solving. We're already seeing this. Specialized AI is better than doctors at diagnosing certain tumors, for example.
