I don’t really think IaC is there yet, as someone who has used terraform (and now pulumi) in production for some time.
My biggest gripe is that the feedback loop is fairly slow: planning often predicts valid config that fails in deployment. It doesn’t help that the process of planning is really slow (see https://github.com/pulumi/pulumi/issues/8872 it can take minutes for pulumi to plan changes if using azblob backend) with little incentive for teams like pulumi to investigate or fix unless you use their cloud. I get that pulumi is in the business of promoting their own cloud, but there are few (if any im aware of) IaC solutions not intrinsically tied to for-profit SaaS because it’s incredibly labor intensive to build consistent interfaces to several constantly changing cloud providers.
