I suspect Inbox was never meant to survive. It had small details that prevented mass adoption. For instance, it took them months after launch to implement an automatic signature, and then they added the artificial restriction to only allow them in your gmail.com account, not other accounts like in gmail. This prevented a lot of people whose workplace policy requires a specific signature, me included, from completely ditching gmail.
