Interesting bits (to me anyway): John Von Neuman and the colonization of Mars [0], the Halting Problem [1].

Love the rabbit holes....

Thanks for the post. There’s a depth to Conway talking about his most commonly known piece of work, and his reactions to it, that gives one a lot to think about.

Also, this is the second time this weekend that I’ve heard John Conway refer to Scientific American. I used to be a regular reader some twenty years or so ago. Is it worth looking into again?

Can anyone point to a longer cut of that video? Seems like they missed a pretty interesting bit at the end!
