Why are you so angry? He gave a talk and released the slides because he thought people may benefit from it - given Jake's (the speaker) background and skills, I would say he's doing everyone a favor by publicly releasing this.
Sometimes you can get a well-defined problem, but finding the "right" analytical solution will take you days of reading up on it, and the chance of getting it wrong is relatively high. Especially if you don't have someone with strong mathematical/statistical background to review your work.
In those cases, finding a programmatic hack around it is a very good approach for giving you reasonable results in a shorter timeframe.
Any idiot can run a simulation, or compute "something". "Something" is only useful in context.
"If you can write a for loop, you can do statistics!" Ugh. Can nobody read anymore? It has to be a "slide deck"?
Jesus, pick up a book and ask some goddamn questions if you're interested.
