    CONFESSION: when I was at I created this image from our CAD model of the rover before it launched. The media loved it and now it’s one of the top images when you google “Curiosity Rover”. BUT they never found proof of aliens on Mars. Alf was right there the whole time :)

    We need some algorithm that can reliably tabulate stats on media inaccuracy, political bias, and negativity bias and create rankings of news sources, so the market could better penalize these things (and reward integrity). Basically the concept of a carbon tax, but for media.

    A bunch of people have sent me this and asked me what I think. I think it's freakin awesome. I've spoken with Shane about it too. He's really, really talented and can't wait to see what else he comes up with. You should subscribe to his channel.

    DM me if you worked at Disneyland in the last 4 years. I have an idea for a video and I want to know how plausible it would be. For unspecified reasons I can’t go through official channels 😬

    Your picture is in my NatGeo Space Atlas book. Looks like they cropped out Alf 😕. That would have been very funny if he was kept in.
