@bthalpin I love this. It is a long-term goal to translate all the models from the book into Julia (and other languages, but Julia is top priority). As you surmised, I chose NetLogo for practical reasons, but I think that serious modelers should be competent in more general languages.
@psmaldino I'm enjoying your book!
#Julialang is a pretty good target. But I think that with the right choices about design, you could translate to Julia, Python and R almost in parallel.
