If jobs are what you are concerned about then I can assure you no company is skipping on software developers because they don't know Kubernetes syntax.
Ansible/Salt/Puppet/Chef/CFEngine are closer comparisons.
It also doesn’t manage your configs; ie if you need to roll back, it won’t do that for you (though git will let you do that pretty easily).
I think Compose is great for the niches it serves; I have a lot of stuff that still runs on Compose because it doesn’t need any k8s stuff yet. I just don’t think it can be honestly called a k8s replacement. Compose offers equivalent features for some kinds of apps in certain situations, but k8s is a broader tool by far (for better or worse).
