Honestly, I can only begin to imagine the implications of something like this...sending our "swarms" into space to explore, as they mention in the article above. Sending our "swarms" to help with rescue missions, building projects, etc.
Perhaps another area where we will have difficulty setting boundaries and avoiding crippling errors in human planning. I don't mean to be "doom and gloom" on this. But it could be a mistake.
