AI is really good as a starting point for literally any document, report, or email that you have to write. Put in as detailed of a prompt as you can, describing content, style, and length and cut out 2/3 or more of your work. You’ll need to edit it - somewhat heavily, probably - but it gives you the structure and baseline.

I’m guessing B will happen first, just because we have so much more control of the environment, but we’re still so far away from either one… Maybe I’ll get to see the early stages sometime in my life.
