Wouldn't a phrase starting with "I did that because...." immediately discredit the idea of freewill?
If only Chaos Theory could speak...
Can we not create a seemingly infinite but finite list of possible actions one might take in a given situation?
Surely, if a system could factor the appropriate variables and vet the possible outcomes with consideration to past actualities via a developed algorithm - 100% accuracy may be possible, in time. I believe achieving anything beyond 50% would be a reason to push further and so do others.
Of course, the computational power would be astronomical but Moore's Law thrives - so no worries.
All things considered, I'm not convinced we'd find ourselves navigating a Mandelbrot Fractal-esque situation.
Nothing is NOT quantifiable.
