This is important: you can separate handling complexity from the profession of building architecturally sound systems. We can teach people how to do math correctly. That doesn't guarantee that they will be able to solve arbitrarily complex problems. But to solve math problems, you MUST at least have the skill sets. So there is a test to measure do you have the skill sets. How much one is willing and/or able to handle complexity is a separate thing to consider.
