  We discuss AdS$_2$ quantum gravity from an unconventional perspective that
emphasizes bulk geometry. In our approach, AdS$_2$ has no boundary, there are
no divergences that require renormalization, and the dilaton of JT-gravity can
be omitted altogether. The result is the standard Schwarzian theory. However,
it may be advantageous that our derivation just relies on conventional AdS/CFT
correspondence and effective quantum field theory. For example, it clarifies
the symmetry breaking pattern. It also puts the non-compact AdS$_2$ topology on
the same footing as compact Riemann surfaces.
