Judging by how popular Powershell has become in these 'GUI-only' ecosystems: yes, a lot of them can and want to.
But I'm not saying everyone always should code. I'm saying that not only wrangling Ansible and Terraform is already programming, it's a difficult kind of programming (no tests, no debugger, usually directly on prod), and that we should stop pretending that it's not. That the industry should stop it with the self-fulfilling myth that sysadmins don't want to program by continuing to build 'DevOps' tools centered around lame DSLs. Give sysadmins real programming languages, libraries and guidance on how to program, not shrink-wrapped tools that pretend they're purely configuration driven yet implement a full-blown programming langauge on top of YAML.
And if i had an euro for every sysadmin who told me "i'm not a developer, you do it", i'd be rich. "Sysadmin" includes Windows-only, GUI-only, ClickOps style admins, which still exist. Do you think they can or want to code? Heck, there are even networking admins that prefer to use GUIs over CLIs!
Not everyone can or wants to write code, even if some people underestimate their skills, some people are afraid.
