No...I did not want to offend "ALL" the old seasoned DBAs. But see yourself around, there are many in this industry who do not welcome "changes". What you are pointing out is nothing but improvement in the software, having faced those problems in old times do not necessarily makes someone a better DBA. Like it or not "experience is not always the best to have", "unlearning curve" is longer than a "learning curve". There are many bright DBAs knocking the doors but what I was pointing out, there are "some" (not ALL) old seasoned DBAs who are in the interview boards, who for some reasons want to see only past experience, ignoring the fact that these fresh guys will bring some new concepts, bew ideas and they ought to be given reasonable chances.
I agree that it is the business and in the business what takes edge over anything else is "professionalism" and "cost-effectiveness". No wonder I hear many old seasoned DBAs mentioning about "bringing down their hourly rates", even though they have so much of experience, they can't command the market...!
