Where are most Professionals with FoundationDB found? And why?

FoundationDB is such an interesting technology, yet there are so few Professionals found with actual hands on experience.
How come others are not learning it?
Are there any training programs, coaching, best courses to learn it?
And if anyone has DBA FoundationDB experience, and wants to work for one of the Leaders in Digital Payments, please feel free to email me your resume.
