the analogy is not accurate and "adaptive object models" are decades 
old.

to take this example, in order to relieve the use of the "operator" 
task, the system would have to accept the assertion, that the even 
occurred, together with a description of its consequences, and proceed 
to rewrite the object metamodel and instance model itself. manual 
changes to the metamodel with automatic propagation to an instance 
model are old technology and are one level lower than the paradigm's 
aspirations.

that's also still one level down.
