  We will highlight that despite there being various approaches to quantum
gravity, there are universal approach-independent features of quantum gravity.
The geometry of spacetime becomes an emergent structure, which emerges from
some purely quantum gravitational degrees of freedom. We argue that these
quantum gravitational degrees of freedom can be best understood using quantum
information theory. Various approaches to quantum gravity seem to suggest that
quantum gravity could be a third quantized theory, and such a theory would not
be defined in spacetime, but rather in an abstract configuration space of
fields. This supports the view that spacetime geometry is not fundamental, thus
effectively ending the spacetime description of nature.
