One of those investor bait ideas where some wide eye-ed dreamer says "what if we take this really cool nascent technology and combine it with this other cool idea that people are talking about, and do something really sci-fi!" With little regard for the fact that one technology is only just starting to be accepted as a thing that really exists right now, and the other has been plateauted for the past several years despite billions and billions of dollars being thrown at the problem. Suffice to say, it's not exactly a matter of just buying a value-pack of robot dogs from the local microcenter and picking up a new autonomous ford transit from the local dealer and stickin' 'em together with some python and a couple of arduinos.
Those kinds of ideas are like a dime a dozen.
