This will absolutely be a commercial failure. I don't harbor any ill will to anybody in the company, and I wish them the best, but a voice interface in public is a complete non-starter. What is the use-case for this device for which a comparably-priced smartphone isn't better...much better? The only real distinguishing feature this thing has over a smartphone is projection, and even that doesn't seem too difficult to tack onto future models.
Once the AI Pin replies with a "sorry, couldn't get that" a few times, people will give up on it and reach for their phones. I could see it finding some success in the accessibility market, but outside of niche applications, I don't think this thing sticks around.
