talked about yeah don't work on deep learning benchmarks and try to improve them by one percent that's a sucky thing to do work on hard things and real robots and that's I think what this class is all about so that's awesome okay and I'm just gonna show a one last video which is one of my favorites just for drones following Jack here as he goes down a waterslide just in in every direction and it's just a fun thing to watch all right cool yeah so we get a lot of sweet videos and again so our goal is to like bring these drones to doing useful
