As others mentioned the titles have changed so the same people are now DevOps, Infrastructure Engineer, Cloud Engineer, SRE, etc...
Sure the work has evolved too but a lot of the fundamentals are still the same and you still massively benefit from having that background context and history.
There are a lot of fresh "bootcamp cloud engineers" who know the buzzwords and know which buttons to click on AWS but they don't have the depth of knowledge to safely navigate on their own.
They can give you a 30 minute spiel about why you must move to serverless ASAP but ask them what 777 permission is and they have no idea.
Not that being a beginner is any issue at all if you are self-aware but some of them are lost in YAML and buzzwords and have no idea about their gaps in knowledge and experience.
