Yes. You need to understand them. The proposed solution doesn’t work for every multithreaded environment, e.g. mobile. You should instead work with threads at the level of abstraction that your skill supports and your spec requires. Some aspects of programming are complex and unintuitive, and that’s OK. If we just wall off those options then–absent a CS breakthrough–a whole class of programs would not exist.
