I skipped through the video and it feels like a stream of consciousness rather than actually selling something specific if that makes sense. Some random thoughts (take them with a grain of salt, I don't make videos): More structure (with time annotations), be more concise! But more importantly, it's often more convincing or interesting to sell a specific idea instead of enumerating loosely related benefits. Examples: "Clojure is optimised for information processing", or similar would be a theme under which you can mention functional programming, the core library etc. "Explorative programming and scripting with Clojure" would be a video to focus on the REPL and maybe introduce babashka. If you want to convince your friends: • Show them a solution to a problem that they didn't even know they had. And I don't mean FUD, I mean real issues and how to solve them. • Show both the benefits and the downsides. A good exchange is "You loose this, but you gain that." It feels more honest that way and puts them in charge.
