At the same time, there are really no 'models' like in, say, Physics or Engineering. The state-of-the-art consists in 'well, this seems to be reasonable and seems to work'. I mean 'models' like 'mathematical models' not like 'a model of a simplified neuron'. Which for a chess/go-winning program is pretty harmless and even interesting. Not so much for autonomous driving and/or security, for example.
