We still exist. Our job titles just changed and more responsibility was put on our plates. Now we do the above work, plus manage automation (Jenkins pipelines, Ansible playbooks, etc) among other work. Not that the increased responsibility is an issue, just that the title makes us seem fancier than we are. I think that is part of the problem, everyone needs some ridiculous title now, a “lowly” sysadmin gets looked at sideways.
