Extremely paranoid people can look like visionaries because they have a lifetime of practicing building convincing narratives, just about almost everything. And they really believe it too, making it even more convincing.
And while having a general ideological guideline is not all that bad. Like how capitalism, or even socialism, in theory, is not bad. But in practice, you have to count for the elements of human characteristics.
This is the problem with paranoid founders. They initially come up with good ideas out of their own “giftedness”. But when the idea session is over, they will have to face the reality of humanness. Which they often know very little about. Because their “giftedness” comes from denying human traits.
