depends which part of rocketry theyre doing. no one can do everything. someone does combustion stuff, someone does fluid valves, someone does pumps, someone does turbines, someone does tanks, someone does harnessing, someone does electronics, someone does software, someone does aerodynamics, someone does structural analysis, someone does gnc, someone does gases, someone does sensors, someone does payloads, someone does testing, etc. no one has to learn all the math so its not like its really the most complex thing ever, just a delicate dance of cooperation. but yeah monkeys couldnt do it cause they cant talk, even if they understood the math somehow.
