Well if your definition of bonafide smart is that they’re an engineer, then there are pretty few. If you think design and visual communication has any value whatsoever, then yeah, lots of people are using it, some of whom are very smart. That’s why they’re worth $20B after all.
I like the community here overall but there are far too many discussions tainted by the implicit assumption that if (royal) you see yourself as valuable then others value is synonymous with their similarity to you.
