Simulation and modelling are great tools in engineering, but it is still very difficult to create realistic models that predict behavior of the real thing well.

Simulation and modelling are great tools in engineering, but it is still very difficult to create realistic models that predict behavior of the real thing well. There are always things you leave out, and sometimes they come back to bite you on the ass. Things like friction, thermal effects, small forces, delays... Stimulating organisms or institutions seems way more prone to errors of this kind. How do you verify that your agent represents realistic behavior of the thing or organism it is supposed to be representing? (Of course, having a platform for models is a great first step, congrats on the launch)
