It's my understanding is that Google X is a marketing / PR platform for Google. Google X doesn't ever need to actually produce anything or create any real-world value because their value is in the PR they generate for Google - keeping them positioned through press as a technology company vs. the largest advertising company in the world. Many of the Google X projects are acquisitions/acquihires purchased to continue the narrative. It's why they never ship products and can't get anything out the door. If this works - it'll be one of the first after billions invested. They've done an excellent job I would say.

It was more like a playground for Sergey while he was still involved. I’m not sure if he voluntary chose to do it or not.
