when i say fleet i was mostly just thinking of it being not much larger than the 4 ships belonging to the AIs listed. Probably a better word for it. Flotilla maybe? Either way, most of the guardians are on the ground, so my own assumption was it would be more likely that ground mission failures followed by consul boarding actions would be what did them in

interesting question that on the specifics of who contributed what to the child Ai, hmmmm. 

Karan S'jet, technically being a brain in a jar plugged into a ship more than an Ai, provided a base human mind upload to work as a baseline template, Adam much of it's encouraging demeanor, ROB it's ability to act in sync with other's commands, and EDI the em warfare and ability to control no ship things.
