Personally I'd love to talk to a bot that's mastered and memorized many books and all of philosophy and science and is also researching philosophy. Imagine getting his/her/their opinion on all the subtle questions life throws at you.
An "AI tutor," of any sort, would be incredible. One-on-one instruction, directly from expert to novice, is leaps and bounds ahead of every other way we commonly learn. It can be so frustrating to research a topic online and find that all the resources are lacking in some way.
The irony is that a lot of philosophical problems are already solved if you dig deep enough, and the real question is how you present the answers to specific humans in a way that they understand, if the question that they asked is even the question they wanted answered in the first place, which it usually isn't.
I agree. Although, to be fair Google Assistant's knowledge graph powered is already pretty awesome.
