“Happy ArThursday!” is how fans of Isaac Arthur greet each other on Thursdays in America as they jump online to watch the latest logical, mathematical, and quite mind-blowing episode of science and engineering implications for the future. It has been a great pleasure to watch Isaac hone his craft and gather a team to help. It’s an amazing channel, and an optimistic view of the future that can sometimes become quite bleak for an environmental blogger like myself.
Isaac Arthur is now #1 for futurism on youtube, and #2 on google (after wikipedia for the various individual key-word topics like Dyson Spheres, Singularity, Post-Scarcity, etc).
