I started my career in 1988.  I've found that a lot of the problems with data are as a result of training gaps.  Each generation suffers the same education gaps so are doomed to keep making the same mistakes.

The problems I see are not isolated to IT.  I do not believe that mankind has adapted to the internet, the cultural implications, behaviours, ways of working etc and that exacerbates the recurrence of old mistakes.  We have the capability to drive at a million miles an hour but the chassis is older than you'd believe and no one has upgraded the brakes!
