This is a kind of macro-historical view of my main assertion on this blog that humanity is entering a critical phase. It is a phase of history from which we probably have a less than even chance of surviving and the only exit states for say 2100-2200 are extinction or a thriving type one civilization that is expanding into the solar system.
One need not agree with everything Michio Kaku (father of modern string theory and the speaker in this clip) says to understand humanities growing crisis. It helps if one has read some of the resources I list on this blog like Diamond’s ‘Collapse’ and Mason’s ‘2030 Spike’ but even without these it is not hard to see the looming crisis or the importance of our species behaviors in weathering it.
