This is a big question for me. The CDK style form of authoring IaC is way better than config files in HCL/YML/JSON. It has some rough edges and I do wish it wasn't so gung-ho on the magical object-oriented constructor side-effects, but it's still a net improvement.
CDKTF looks promising. How will OpenTF interplay with it?
I'm not into the CDK at all to be honest but isn't it a glorified preprocessor that generates the JSON representation of Terraform input, which is then processed as usual by your regular Terraform binary?
To each his own I guess. I personally like the HTML-like mental model that HCL gives me. In a sense not being a programming language is to me a benefit. If anything, I'd love to see an equivalent of CSS to Terraform - an idea someone smarter than me was floating not so long ago. Decoupling structure from specifics - I can see a well thought-out implementation of this concept actually taking off.
Re: programming languages... I love programming. Just not my infra.
