I literally had a "senior cloud architect" tell me that he didn't understand how one of his team's apps works because "he only draws the boxes" and then laughed it off.
This is why self-deprecating humour can be dangerous. Some people won't get it and will just think you're an idiot.
Don't worry, he knows what you're thinking. It's probably a paralysing deep sadness for him.
I think there can some some truth to that. As I progressed into more architectural work, you have to leave the deep technical details behind, and you do miss it. But you can't do everything.
