If you have minimal automated tests then: Is it better to have automated all the AC but not considered what layer you are automating at and probably duplicating effort OR aiming for more maturity by discussing what can be automated at each layer and avoiding duplication?

You've joined a new company and one of their QA pillars is to encourage an automation first mindset and, if possible, achieve 100% automation.

Does this approach make perfect sense to you OR What questions do you ask to understand what this means?
