But humans being able to develop new tricks is core to their intelligence, saying its just a bag of tricks means you don't understand what AGI is. So either the poster misunderstood Dennett or Dennett weren't talking about AGI or Dennett didn't understand this well.
Of course there are many tricks you will need special training for, like many of the skills human share with animals, but the ability to construct useful shareable large knowledge bases based on observations is unique to humans and isn't just a "trick".
