Infra-as-code is mainly just a method to force people to write things down, rather than the default of nobody writing anything down, and people just manually making changes that nobody else knows about, making it really difficult to manage changes. Even a bash script that creates an ec2 instance is infrastructure-as-code.

OTOH, I kind of hate Terraform now, because you can use it in a way that will surprise you and blow up, leaving a mess that you have to clean up manually. It's more "infrastructure as code" than Ansible, but Ansible will at least attempt to fix things that aren't "right". So everything that has a certain label is not by definition superior to all alternatives. (I actually hate both tools for different reasons, but they have their uses)
