I wrote about Sandbar, the NYC startup looking to ship an AI note-taking ring, Stream, this summer. Part of what I found interesting about it is the wider race to try different form functions: earbuds, necklace, pin, wristband, now ring. But part is also that Stream is meant to be fully single-player and non-invasive. You raise your finger to talk to the ring in a conspicuous, les s surveillance-y way; Stream only listens to your voice, when you're actively tapping it, instead of being always-on. Does that mean you won't get weird looks on the subway? I'm not sure -- and candidly not sure I'd use it every day. But the care that founder @minafahmi has put into the product's form and function makes me think they have a shot.
