    Fermi Paradox

    Fermi Paradox

    Ever wondered where all the aliens are? It’s actually very weird that, as big and old as the universe is, we seem to be the only intelligent life. In this episode, Josh examines the Fermi paradox, and what it says about humanity’s place in the universe.

    Great Filter

    Great Filter

    The Great Filter hypothesis says we’re alone in the universe because the process of evolution contains some filter that prevents life from spreading into the universe. Have we passed it or is it in our future? Humanity’s survival may depend on the answer.

    X Risks

    Humanity could have a future billions of years long – or we might not make it past the next century. If we have a trip through the Great Filter ahead of us, then we appear to be entering it now. It looks like existential risks will be our filter.

    Natural Risks

    Natural Risks

    Humans have faced existential risks since our species was born. Because we are Earthbound, what happens to Earth happens to us. Josh points out that there’s a lot that can happen to Earth - like gamma ray bursts, supernovae, and runaway greenhouse effect.

    Biotechnology

    Biotechnology

    Natural viruses and bacteria can be deadly enough; the 1918 Spanish Flu killed 50 million people in four months. But risky new research, carried out in an unknown number of labs around the world, are creating even more dangerous humanmade pathogens.

Wishing for season 2

Exciting, educating, and eery! I listen with morbid fascination to the extrapolations and genuine concern for the data and facts used to effectively illustrate the reason of these projections.

Most of these topics have had interesting developments since this show’s release! There is new data, new insights, new technology.

I’d love to hear more!

I just finished listening to the whole series straight through. Great stuff. Everything is well explained and well organized. Fact of the podcast for me was that A.I. doesn’t love me or hate me, it just was to use my atoms for something else.

Mixed feelings

It’s good so far but also sometimes it’s interesting and sometimes it’s terrifying
