True, but now that's all it has for large swathes of urban landscape. It's tremendously alienating, nothing but startups texting each other. I figure it's only a matter of time before we see billboards with QR codes or interference patterns designed to make self-driving taxis halt in their tracks so that some security/ alignment/ infrastructure startup can get its brand amplified by giving people something to complain about.
