First, I've loved that Google open sourced Tensor Flow Federated as a way to encourage the rest of the world to adopt this method of decentralized machine learning.

Second, I was a bit disheartened that this concept had to be explained with a comic strip to make it accessible because I hoped the benefits were clear to everyone.

Third, I read the comic strip, learned new things (secure aggregation protocol, wtf, amazing!), kicked myself for being smug and appreciated the huge amount of effort that someone invested to communicate this.
