There is a big problem with how we work with ai-generated artifacts, but I don't think creating another google-docs-like suite is the answer.
LLMs are very good at working with Markdown, and are way worse with xml-based rich documents. The problem is, we have established collaborative rich docs, but no collaborative markdown-based docs.
For example at google, all your system design docs will end up being written in google docs, because it can be easily shared with granular access, people can leave comments, it's well integrated with other google products. But once your doc is in that complicated format, there's no way to iterate on that with an agent: it's gonna inevitably destroy your formating, overwrite some of your edited content, and you can't even have a nice line by line diff like you'd have when you work with a simple text format like md.
Building a nice collaborative markdown editor to the level where it competes with gdoc in popularity, at least in software engineering circle, would be the answer.
Same with sheets. Some stripped version, which is as close as just "csv editor with some better visuals" would be much more ai-friendly
