I would agree here. Much of Wave was put into Google Docs, Drive, etc., as well as various other Google office collaboration products. Yes, Wave itself died, but it didn't fail.

Google does this with a lot of their stuff, it seems, too. Google Glass, for example, spread into so much of Android and further: Ok Google for the Assistant came from Ok Glass; the timeline made its way into Google Now and eventually into Assistant again; heck, you can see the beginnings of Material Design in the Glass UI. Google makes a ton of experimental products only to axe them swiftly and put their remains into new products.
