learning algorithm knows who all the messages on the network really came from and I think it's important to build security into a new technology near the start of its development we found that it's very hard to build a working system first and then add security later so I am really excited about the idea that if we dive in and start anticipating security problems with machine learning now we can make sure that these algorithms are secure from the start instead of trying to patch it in richer actively years later thank you fellas
