1. the future should continue to need qualified people. if the future did not look good (to me) i'd not be here to answer this.
2. the worst "thing" to hit our industry in the last 10+ years is certification without qualification. some employers (especially where proven talent is scarce and the interviewer has no clue about what a dba does) use certification as a screening tool. not the best way to screen (imho).
3. my last several clients have policies that preclude giving out organizational information. my title is whatever the contract called for (dba, senior consultant, contractor, etc). i usually just call myself a Migrant Data Worker which i have been since the early 80's.
