We look at a lot of scenarios for what might happen in the future -- cool technological developments, major advances in science, new evolutionary developments for humans and for other species on this planet -- but are there any future developments that we can say with any certainty will happen?

Hosts Stephen Gordon and Phil Bowermaster introduce the Inevitablity Scale, a tool for gauging whether a specific future outcome is inevitable. We will take a look at how some future events stack up when measured for inevitability:

The Next Presidential ElectionThe End of the WorldThe First Manned Flight to MarsThe Emergence of Greater-than-Human Artificial Intelligence

What can we say for sure that we know is going to happen? Tune in and explore.
