Just because you didn't know about the concept doesn't mean the distinction is nonsense. I think they are similar but not the same, exactly for the reasons laid out in the comment you are replying too. Just because you hate the languages that support concurrent programming doesn't mean concurrent programming is meaningless. Any language using async/await (basically all of them these days) support concurrent programming, including languages such as Swift and C# which are nothing like Python or JavaScript.
