From the (thin) copy here, it appears this is very much what Google Wave wanted to be, including an API for stateful robots that collaborate alongside you. Hopefully the API layer will allow for custom presentational components, allowing developers to go beyond simple "office-like" use cases, into multimedia creative applications.

Reminds me a lot of Notion.so (https://www.notion.so) which got me to move away from OneNote for the first time for about a year, but the lack of pen support forced me to switch back.

Having all the data in the "document" stored in a database of sorts and then being able to pivot the display and reference and pull in across different surfaces was a very useful in practice. From the copy and mockups also might be fair to view this as a mashup of AirTable + Access + OneNote.

Kind of what OLE was supposed to be back in the day? Just web based this time? It seemed like Microsoft's pushing of the document component object model never really stuck back then as people gravitated back to monolithic text documents and spreadsheets for the most part. I wonder if it will work this time.

Now even Microsoft is releasing the next generation of document creation tools as cloud only. Does anyone still think that we will do the thin clients to powerful personal computers transition for mobile too? I really wanted it to happen but I'm losing faith.

So Microsoft office can finally do what Google docs did more than 10 years ago?
