"inspector" is a made-up label for this type. It's not some law of nature, just an approximation for a common social role of this type, especially for the normalizing subtype LSI.
A talent for technical fields, leadership. Ability to push through difficulties. I don't think LSI typing is in any way strange for Elon Musk.He types people who are known of being an exact opposite of that as LSIs. Intuitive innovators who push boundaries of what's possible, like Elon Musk for example.
