Really well done. The pacing of this second episode is very good.

Lish appreciates your observation! Yes, the animator of The Advanced Apes is finally a part of hubski!

I'm curious what a simple extrapolation of the current increase in expectancy gives for the year 2100. Is there a Moore's Law for life expectancy?

Great question. Aubrey de Grey has introduced an important concept that doesn't function quite like a Moore's Law, but helps us conceptualize what it will be like for us to age. He calls it "Longevity Escape Velocity" (LEV). This is a quantification of our aging that attempts to describe whether we are aging faster or slower than technological evolution. He hypothesizes that for us there will come a point where people that would normally be dying at a high rate (70-100 year olds) will start to get gradually "younger" biologically and their death rate will actually start to decrease (perhaps dramatically). When this starts to happen we'll know that we are reaching the "Longevity Escape Velocity" and that people younger than 70 will likely be aging slower than technological evolution (and will therefore have a new life expectancy of 1,000 (because this is how long you would live on average if aging didn't cause death).
