To first order, this is always true. It should also be noted that computation happens on a desktop computer.

For quadrotors at least. Most of the projects I've seen coming out of Boston Dynamics are, as best I can tell, entirely self-contained. (This is part of why BD impresses me so much)

  I may not be fully up to date but I have never seen a BD video with cooperating robots.

  Yes, but none of them are (permanently) aerial and some of them use internal combustion for power. Computation requires weight and energy, and computer vision requires lots of computation.

  Aren't most of their videos using a tether though? Which is pretty much the same "only works in the lab" issue.

Projects using quadrotors to do things like fly cooperatively and do acrobatics [1,2] will often use high speed motion capture systems with multiple fixed cameras. This decouples the problem of perceiving the environment from the problem of responding to the environment. More broadly in robotics there are plenty of people working on ground-based robots that don't rely on multiple fixed high speed cameras - self-driving cars [3] would be one example. There are also people working on cooperative ground based robots that don't rely on multiple fixed high speed cameras - for example, the RoboCupSoccer Middle-Size League [4]. There are also people working on quadrotors that don't cooperate/do acrobatics and who don't rely on fixed vision systems - for example people working on autonomous quadrotor mapping [5] and using IMUs and on-robot vision [6].
