Our Past (and Future) With Supervolcanoes

I recently interview paleoecologist Dr. Robert Dull to discuss his recent discovery that there was a volcanic eruption in 536 C.E. at Lake Illopango in El Salvador.  How did this eruption impact the ancient world?  And how can we use our knowledge of past supervolcanic eruptions to better understand their future threat to our species?

Another Earth

Recently, astronomers have been discovering more information about the frequency of Earth-like planets in our galaxy.  A study yesterday revealed that several Earth-like planets could exist within 10 light-years of our star system.  If true, the James Webb Space Telescope could theoretically take direct photographs of other Earth-like planets in the 2020s.

21st Century Neanderthals

Thoughts on the Future pt. 2

I frequently encounter thoughts from people about the future that follow a classical dystopian futuristic narrative.  Although creating these narratives may serve an important function, they do not adequately explain our likely future trajectory.  Throughout the 21st century, we need to start to rethink how our species evolves, and how we solve problems on a global scale.

The Substrate of Mind

The likelihood of a transition to a planet dominated by non-biological intelligence is essentially dependent on one large philosophical assumption: that the substrate of intelligence and consciousness is unimportant.  Although I contend that this is currently an unanswerable question, the answer may define our future.

The Human Neocortex

In How To Create A Mind by Ray Kurzweil, the importance of the human neocortex is explored.  What is important about the human neocortex?  How did it evolve in our species?  The answer to these questions can shed light on one of the most important evolutionary developments in the history of life on Earth.
