This isn't a webapp, it's a wizard for naive prediction of the date of the singularity (you seem to mix AI with a very narrow form of IA). You're not quite "modeling" a future world. Java sucks for this - why use it, given the current state of javascript and canvas?

This would make an interesting blog post if you distributed the various "viewpoints" on the various questions into a bunch of images.
