Google co-founder Sergey Brin said today that it was "probably a mistake" for him to have worked on Google+ because he's "not a very social person." Speaking at Recode's Code Conference, Brin — who also called himself "kind of a weirdo" — 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 was misguided. "It was probably a mistake," he said, "for me to be working on anything tangentially related to social to begin with."

Brin, who co-founded Google with Larry Page in 1998, said his attention is now on his company's semi-secret skunkworks 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. Brin used the Code Conference to announce the lab's latest creation: a self-driving car that navigates without a steering wheel.
