BLock shoots block is just fine for a 4th grader - at least it is for my kid. And I think computers are knowable. Some languages are not, but others are. Ruby has a REPL that's very good as a teaching tool. I've had a lot of luck teaching with that. C++ on the other hand, or even Java, not so much. I know it's harder than it was, but we could change that as long as we don't decide to fail by defeating ourselves.

With knowable I mean that you could at some point in the past literally know each line of code present in the memory of your machine. That's no longer the case.
