The harder you declare a technology dead, the more obvious is its enduring existence. So no anger here, all these things are still needed. But it's obvious, that there are technologies and practices that are less important that they were a few years ago. Here's Computerworld's list. It includes: Cobol, nonrelational database management systems, non-IP networks, cc:Mail, ColdFusion, C programming,
PowerBuilder, certified NetWare engineers, PC network administrators, and OS/2.
Got any of these? Some more suggestions?
