Creating a nice PPT is actually hard because it requires visual capabilities and so-called "computer use" (really, GUI use) of fiddly proprietary software. The nice thing about the coding case compared to a lot of disparate white-collar work is that it's all plain ASCII text. You can already ask a coding model to create a nice TeX/beamer slideshow (or whateve the Typst-based equivalent is) but whether the boss will be duly impressed by that is anyone's guess.

This is a tangent but I'd also mention sli.dev -- slideshow-as-website is really great and fun to make with llms
