That said, I also don't think you need to be an expert neural network wrangler and genetic algorithms shaman if you want to study "true AI". You should however have an understanding of the fundamentals behind the techniques used in classical AI so that you can rationally dismiss them, or hell, maybe you'll even find some amazing lead or inspiration in the existing work. After all, the field of AI did start out with ambitions of creating "true AI" (whatever that is).
