I care to disagree because you just move one abstraction layer higher and again you will use sed and awk.

To move stuff to that cattle and to maintain cloud environments, to prepare k8s clusters and manage those. To create docker images or to maintain servers that are running k8s.

You still have AWS console and Azure CLI or GCP console and configurations that need to be search/replaced. You still need to parse logs to understand what is happening in multiple environments, which I would say makes it even more important to be good with unix-fu because you have to find that one broken cow to put it out of misery.

Those command line tools are still useful and used.
