But we can already know this:  because of the complexity of the world, we need something of 
the sort. And it is clear that we need new benchmarks to push our systems to do the 
kind of sophisticated reasoning that the Romeo and Juliet scenario exemplifies. Because 
we can neither encode every scenario in advance, nor hope always to interpolate 
between known cases, a reasoning system that can leverage large-scale background knowledge 
efficiently, even when available information is incomplete is a prerequisite to robustness.   

Recent work by Minervini et al (Minervini et al., 2019) gives me hope that a 
neurosymbolic hybrid approach could break new ground. Besold et al. (Besold, Garcez, 
Stenning, van der Torre, & van Lambalgen, 2017) offer another starting point. The very 
fact that people are trying gives me more hope; reasoning and knowledge need to be 
first-class citizens if we are to move forward, and it is good to see people trying.
