It seems to me that the DBA skillset scale is sliding more to the software/softskills side and further away from the hardware/hermit end. Cloud computing is continuing a trend begun with SANs and VMs IMO. I'm more concerned over the last few years with communicating performance requirements and coordinating with the SAN and VM guys than specific hardware issues. That's been the biggest adjustment so far, however I prefer it that way since it gives me more time to organize data.
