The video was made in late 2016 by Nick Foster, the head of design at X (formerly Google X) and a co-founder of the Near Future Laboratory. The video, shared internally within Google, imagines a future of total data collection, where Google helps nudge users into alignment with their goals, custom-prints personalized devices to collect more data, and even guides the behaviour of entire populations to solve global problems like poverty and disease.

When reached for comment on the video, an X spokesperson provided the following statement to The Verge:

"We understand if this is disturbing -- it is designed to be. This is a thought-experiment by the Design team from years ago that uses a technique known as ??speculative design' to explore uncomfortable ideas and concepts in order to provoke discussion and debate. It's not related to any current or future products."
