At the moment I unfortunately don't have enough cash to invest in betting projects.

Fortunately, that's why we have PredictionBook! Looking through my compilation of predictions (http://www.gwern.net/hpmor-predictions), I see we already have two relevant predictions:

• Harry will create a superintelligent AI using magic or magical objects

  • and it won't be Friendly, killing many/all

(I've added a new more general one as well.)
