It seems to be UI/UX for creating//editing//managing databases and interacting with them for non-programmers.
Paraphrasing the video: Like sheets, but with structured data (columns define data types with relationships) and complex actions/triggers via bots.
Per your original comment, given Google's track record with customer performance//services being dead on arrival, I can imagine few here are interested in learning//migrating their workflow just to be locked out or migrating away not long after.
I'd link to the myriad of hn//twitter//medium posts used to get customer support through bad press, but I'm on mobile, I'll leave that as an exercise to the user.
