I think software people tend to underestimate the value of superficial familiarity. By all means, adhere to your new concepts and mental model. But even things like coloring, placement of the menu bar, the icons that you use, the organization of the UI, etc can go a really long way

Think about programming languages- ones that introduce radical new concepts may still employ familiar syntax/naming to smooth the transition for newcomers. Rust mimicked C++, TypeScript extended JS, etc. These languages were made to introduce powerful new ways of thinking about code, but by appearing as similar as possible to what devs already knew, they freed up more brain cycles for people trying to adopt them. They didn't muddy their concept-space for the sake of familiarity, but they didn't introduce any more unfamiliarity than they actually needed to for the benefits they wanted to give
