Devops usually means "it's faster and cheaper because we don't have a dedicated sysadmin". The union of good developers and good syadmins is narrow like that of developers and designers.
Maybe true of junior devops that has never done any sysadmin or much programming outside of school. Theres always people who are skilled at their job in whatever field.
Yeah - careful with that generalization though... talent is more a person-to-person and organization-to-organization thing and not a specific title IMO
