Whether someone is in a rut or not is a separate issue than whether they've worked with terraform. The key here isn't what technology they've used, it's a mindset towards automation. I recently came off a project that was technically using "GitOps" but where every deployment involved copying and pasting dozens of files across 3 or 4 repos, and the whole thing was very error prone, and if you didn't change exactly the right things your service would just silently fail to deploy, or be unreachable, with zero feedback. I've worked at a company with a bespoke CI/CD system hacked together with PHP scripts and Jenkins servers, but where every single process was ruthlessly automated, reversible, with multiple layers of fallback, failure recovery, garrulous feedback, and built-in approvals that you could automate, or if you didn't remember, you'd get a helpful reminder in email and a link to a page to fill in the required information. People could, and did, know how to do a deployment on it their first or second day. Guess which one was more pleasant to deploy with? It's the automation mindset that's important. You can find people with the right mindset who haven't had a chance yet to play with ansible or terraform, and you can find people who manage to create nightmarish complexities of manual processes out of ansible and terraform. Unfortunately, I haven't yet found this to correlate much with years of experience.
