I wouldn't call myself a c++ expert but I have used the language for a long time. In my opinion, templates have a lot of awesome uses outside of SFINAE and if you find yourself reaching for SFINAE, that's probably code smell and you can probably simplify the design elsewhere to avoid it. Generally I find the best use of templates is the most basic: you want to write some code that operates on duck-types. As long as one is able to control themselves and pick the right use cases for maintainability, templates are simple enough. In my experience, this is very doable. Concepts are also a really cool way to rein in which types are accepted as a template parameter and have a lot of potential to make templates easier to understand and teach. To me, this is the most exciting c++20 feature.
