I am not by any stretch of the imagination a DBA - I am a database developer. However, I can see where jobs may be cut. Yeah, sure you will still need a DBA or 2 in your company to run your servers, but will you need 10?

The question is not: will the DBA become extinct?

The question may be more: will one future DBA now be able to handle the job of more than one current DBA?

And this will eventually happen as technology makes DBAs lives easier. If you are a DBA - keep your fingers in the development pie - the more skills you have, the better off you are.
