I haven't listened to the podcast (but may give it a try). So this is only responding to your brief comment here, and playing Devil's advocate. 1. Bitcoin is not a life-form and thus does not need to evolve to avoid going extinct 2. Bitcoin is an intellectually created system of abstraction, with some technology incorporated to prevent it from (easily) being changed 3. Synthesizing points 1&2, Bitcoin can not change (or 'evolve') by itself. It needs collective (consensus) human agency to change. As its collective value and worldly 'weight' increases, the core features of Bitcoin are probably less likely to change, except when there is broad consensus that any change has become absolutely necessary. Indeed, I've seen it argued that after the first block had been mined in January 2009, the design of Bitcoin had been essentially 'set' for all time.

All logical - 3 is a strong point to my cocktail based rambling. My bias is to think of Bitcoin in biology terms because that’s when I first encountered game theory. Through that lens I had my first “oh sh**” moment when reading about Bitcoin. I think that software needs to improve and change to stay relevant but I need to distinguish protocol from regular software. Thanks for the reply.
