Because after all, premise three: 'All purely physical systems are subject to determinism.' Isn't it true after all that the basic laws of physics are deterministic laws?
What this really means is not that we should avoid evaluation, but that everyone in the process has a responsibility for how they calibrate the physics of their role within these systems.
This is especially true at very large and very small scales (think astronomy or particle physics), but also liminal spaces or large sociotechnical systems that cannot be experienced completely or directly (think cyberspace, but also large infrastructure systems like power grids, interstrate highway systems, etc.).
"The physics of flight at such small scales is relatively poorly understood which makes designing small flying systems very difficult, " he told BBC News, adding that biological systems provided "critical insights into designing our own artificial flyers".
