The AI term is banded around like coffee at a dev morning these days. It feels ironic that we, as a thinking species, have stopped thinking or debating what "intelligence" means though, and restrict it now to single domains. DeepMind is intelligent so long as you're only doing one thing - playing Go.
Proposal for definitions of "intelligence" to include more linkage. Has probably been done a thousand times before.
1. Empathy. Is "an intelligence" linked to others? Can it teach someone with understanding?
2. Transferable skills. Can "an intelligence" apply abstract concepts to other domains?
This is especially relevant to game-playing intelligence as games are inherently a mental training ground. Chess teaches strategy. Poker teaches empathy and bluff. Go teaches empty space and the flow of yin and yang. What does "an intelligence" learn about anything else?
3. Mindfulness. Does "an intelligence" gain an understanding of itself? Could it teach itself to learn better? Why is DeepMind called DeepMind if not?
As it stands, humanity is falling into the standard modern productivity trap of assuming intelligence is good for doing a single task well, and all society requires is to do those tasks better.
Playing Go is not a job.
