Tl;DR: Google X is a subset of Google for researching technology concepts. Taara used to be under Google X but is now spinning out to its own company.
Taara is spinning out of X to become an independent company with a mission to bring high-speed, affordable and abundant connectivity to people everywhere using beams of light.
I’m predicting they build it in just 2 or 3 cities, then quit.
Again.
Google fiber apparently still exists.
I was very surprised to find that out just now.
