Gary,

A cross specialized dba will not be out of a job with mongo, but a sql
admin will. Your perspective (shared by me) is hard to see for those
who are married to their specialities.

However, I will add one caveat to your statement. When a system gets
to a certain size, it behooves the IT team to segregate dba developer
and admin roles. From a change management perspective it creates
barriers that simplify documentation and auditing.
