re: Google Glass essentially flopped...

Fanboys fighting each other is a battle we all lose.

Glass is definitely a commercial failure, but it is questionable if the project ever reached the stage of having commercial goals. Google's #1 product is user data and they are constantly looking for new ways to get it. Another flop of Google's was Wave. It attempted to combine chat/email/blogging all into one app. It Flopped, but I'm pretty sure it's components/lessons moved on to various Google Plus parts, another commercial failure, but not a user data acquisition failure as evidenced by breaking up Plus into multiple separate apps that people did find useful and continue to use and allow Google to access their personal data. So that is 2 flops that still furthered Google towards their end goal. Glass may have been a flop, but that doesn't mean it wasn't/won't be useful to Google.
