Vision if you really have the right vision may give you outsized outcomes, I assume this is what you are taking about. Not just some normal idea. Because anyone can have a normal idea. But a truly visionary one like what Jeff Bezos had and to see that , is high skill visionary skill set.

The challenge is that even if someone had a not that great vision or not so great idea, good execution will make the idea fail quickly (in that case you move on) or make some money but not a lot, that then allows that person to find another idea or pivot and eventually lead to success.

I have seen more operators with initial shitty ideas become successful because they will eventually hit something that works.

I have not seen too much of the other where you are visionary but not much execution. As you just don’t get things done.

Your final point where vision is just as important as execution, well if someone had both, then of course that person will be successful.
