19:43 Yeah. And it's interesting with, like, in little even little tiny things like, you know, Python libraries or a Pytest plug in or some little extra feature, we've got we've kind of gotten lazy. I think some of us have gotten a little bit lazy with CI and say, well, you know, even if, it's okay if it's it's just a few minutes. And and then, like but I'm running it on, on 6 different versions of Python on 3 or 4 different hardware platforms
15:52 Performance is it's important because if it's too slow, people will just assume it's broken. Right? Yeah. But performance is tough because it, like, it is a little wiggly. How do you deal with that?
25:45 I haven't had the opportunity to to use Rust across the, like, Python boundary, But it's really cool, and it warms my heart that we can do things more safely with a little bit less c in the world.
