1. Google's solid track record of killing things because they didn't grow quickly, after a half hearted effort. Stadia being the latest example.
2. Google being pretty bad at cracking the corporate communication space. Teams and Zoom ate its lunch.
3. Google not having a strategy behind communication tools in general. Meet, Hangouts, Chat, Duo, Alo, ... already it's weird where this fits.
4. Google being bad at supporting new hardware gadgets. My Daydream VR came out 2 years before my Pixel, somehow these two things don't support each other.
I wish they at least would sell their divisions instead of kill/hamper such moonshot products. This looks like the next Google Glass.
