Thanks Patschwork ! :)
That drawing is pretty old, I remember it has given me the signal that it could be worth pushing the effort on drawing, until then I wasn't conscious I had some affinities with graphic disciplines :)
About, "all brains together"... Besides "a big reddish and white slimey wobbling thing" as an answer, I'm afraid we can see what it does by looking around us : they might neutralize each others by generating a plethora of useless creative-energy-consuming and conflictual situations.
That said, there are also plethora of good collaborative stuff... So the big reddish wobbling mass might also have its good sides :D
