There is no fool-proof mechanism to test "smartness". IQ tests are not scientific.Think that in india a lot of childs arent going to school and dont know how smart they are. By having a truck whit a mobile EEG and going from village to village you could find some childs that are very smart and by granting funds from goverment maibe their parents would accept to leave them to school. Maibe companyes interested in finding smart kids would offer them the money and a pre contract.
Technology is not science. Simulation has it's limitations.I ask miself why is so hard to make something for the army today when modern computers make all. For example for a tank armour properties of metals composites and mix of materials can be inserted into a computer program. All perodic table can be inserted. Angle calculation shape of tank disposal of optics weight calculation can be inserted. Space in tank can be simulated. Velocity of tank spikes consumed work potential energy resistance of air can be inserted. For a electrif circuit kirchoff laws resistors battery elements electrolites. For a radar electric curent waves weight of trucks cost fuel and all. All can be simulated. Best electronic arangement for reduce weight.
