From my own observations working at a company with a visionary CEO/founder, people with personalities like this tend to kinda balance each other out — so you need more than one. The CEO would suggest some batshit crazy idea, but the engineering lead would bring it down to earth and make it practical before even beginning to discuss it with the rest of the team. If there's no contention, no one to keep such a person in check, no other visionary person to criticize their ideas and ask the right questions, these batshit crazy ideas end up getting implemented and shipped as is. Guess how I found out.
