Brin acknowledged that he used Google+ to post pictures of his kids to his family, but suggested that any previous professional focus on the social network has been misguided.
According to The Verge, Brin said that it was probably a mistake for him to work on anything that is tangentially related to social to begin with.
Brin, who co-founded Google with Larry Page in 1998, said that his attention is now on his company's semi-secret skunk works group, Google X.
Google X is working on a range of projects, including a contact lens that measures glucose, in addition to augmented reality wearable device Google Glass, the report added.
Speaking at the Recode's Code Conference, Brin also announced the lab's latest creation that is a self-driving car that navigates without a steering wheel, the report further added.
