The correct analogy (as we are generally not building people) is "Building an aircraft, that needs a pilot with certification and a certain number of flight hours, or building an aircraft that can be flown by any passanger with minimal instructions, if the need arises". In the latter aircraft, you still benefit from an experienced pilot, but at least, if they pass out, get drunk or plainly go rogue, you still have a decent chance of dealing with the situation, instead of just crashing.
