Billions are being spent by DeepMind and OpenAI explicitly targeted at AGI. Not at all... You don't seems to know a lot about AGI. Google, openAI, Microsoft, Facebook, Baidu etc, do NOT fund AGI. They don't fund AGI nor have even a sketch of a roadmap. They fund narrow AI, that is: they fund researchs on specific problems not on an architecture for general intelligence. Moreover, they only fund statistical AI, not causal AI, which is a pathetic local minimum. What you are looking for is opencog or Cyc.
