"As well as computer scientists, I know of several DBAs who were once professional musicians, actors, hairdressers, artists, scientists, athletes, soldiers and even solicitors and architects. They all make good DBAs too. If only developers were able to bring such a range of skills, experience and knowledge to the job!"

The trouble is, not everyone can program. I'm a developer, and I've met many people in IT that by their own admission cannot program in any language - and I've certainly encountered developers that really should be doing something else! Your statement, quoted above, implies that anyone can become a DBA 😉
