Don't work under non-technical people who believe in hand-waving.
Even if they are well meaning and fair, eventually they will hit a comprehension limit. At that point arbitration for any technical debate should be escalated to a board of suitably qualified people, but they will be unwilling or literally unable to do it. Eventually as a consequence bad technical decisions will be made.
That's the best case scenario. In the worst case scenario you're already undergoing, your boss has no clue who's the better dev or why in your team.
