I'm thrilled to see apps like these, because I believe the greatest potential AI has is to help people be really smart and educated with better judgment. Whether it improves critical thinking by asking challenging questions, or it has you think through complicated scenarios (even just things in your life), or teaches subject matter in an adaptive way that makes it really easy to get things, or just makes learning come to life (your own personal professor).

It's sad none of the leading voices in AI talk about this potential, have they ever? The ratio of talk about apocalypse or singularity to things like this probably tells you something..
