GUIs are nice to set up experiments, knowing what you can set up and changing stuff quickly. For example, setting up a network and a subnet from scratch, creating a VM, connecting to it from the browser and setting up stuff. Could you do that with PowerShell, the CLI, ARM templates or Terraform?

Yes, but it'd be slower since you'd have to go through the docs to find the name of what you're looking for and typing it. Then type another command to see if the changes were applied. Another one to test the result... A huge PITA for experimenting.

Of course, for actual production use, you should definitely have some sort of IaC set up and use that. But for testing or home use (see the tech guy that uses a storage container and Front Door for a static website) the GUI is good enough.
