Some more modern languages - eg. Swift – have "sendable" value types that are inherently thread safe. In my experience some developers tend to equate "sendable" / thread safe data structures with a silver bullet. But you still have to think about what you do in a broader sense… You still have to assemble your thread safe data structures in a way that makes sense, you have to identify what "transactions" you have in your mental model and you still have to think about data consistency.
