I haven't encountered any Chef code in almost ten years. For the stragglers not yet primarily on Kubernetes and Terraform, I see Ansible and some extra Terraform. Maybe I see some Salt here and there.
These are just my anecdotes, for sure, but (also anecdotal) I rarely hear of other "ops" type people using Chef, and most of the ones I know never got more than just their feet wet with Chef (the SaltStack beta was out early enough to avoid Chef).
