Could be interesting/useful, but none of these seem to have any impact on the sites like Youtube which loads tens of megabytes of resources, and every interaction takes a second or so to happen.

Other sites like Photos are fast and performant, but I wonder if it's due to whatever perceived advantages of Wiz or due to the team actually caring: https://medium.com/google-design/google-photos-45b714dfbed1
