AI programs are brittle
Symbolic AI programs use rigid rules & data structures and can't adapt to fluidly to changing environments & ambiguous circumstances. Symbol structures are brittle—they break apart under the pressure of a novel or ambiguous situation.
Note: Versions of this claim are widely discussed in the literature and on these maps. For example, brittleness is discussed by Hofstadter (see "The front-end assumption is dubious", Map 1, Box 74), Brooks (see sidebar, "Postulates of subsumption architecture", on this map), Dreyfus (see sidebar "Postulates of Dreideggereanism" on this map), and the connectionists (see Map 5). It is also raised in the context of fuzzy logic.
