Depends on the situation. I’m thinking of 1-click tools like Tor browser - sure you can be a Tor power user, but maybe the “normie” in this case is a less technical journalist or activist. They need secure defaults and a tool that does its job and stays out of their way. Less options, less room for error.

We can't all be power users of everything, we're all the "normie" in some facet of our lives.

On the flip side, it could be that "UX for normies" is a becoming a trendy excuse for lazy UX. Maybe we need to try harder to find intuitive ways to represent more complex functionality, without removing the need for people to think and make decisions for themselves 🤷
