The whole GSuite (Google Docs, Google Drive, Etc.) have been very productive tools in my experience. (Although Google Drive was launched in like 2012, and Docs in 2006)

The Dart language and Flutter framework have been a rather innovative attempt at making cross platform apps.

But yeah, the amount of innovation at Google has certainly decreased over time.

The gsuite is very much a product of a bunch of acquisitions:

That's not to say Google didn't do a ton to advance the concept, but it wasn't their idea originally, and they acquired a lot of the technology.
