I think OP's point is that "hope" is never a substitute for "a battery of experiments on dependably constant phenomena and supported by strong statistical analysis."
Honestly, this sort of programming (whether it's in quotes or not) will be unbelievably life changing when it works.
I can absolutely put into words what I want, but I cannot program it because of all the variables. When a computer can build the code for me based on my description... Holy cow.
Scientists fold proteins, _hoping_ that they'll find the right sequence, based on all they currently know (best guess).
Without hope there is no need try; without trying there is no discovery.
