  I state a conjecture asserting that for all generic klt Fano varieties X,
there exists a generalised cluster variety U and a surjection from the set of
torus charts on U to the set of toric specializations of X. I prove the
conjecture in dimension 2 after work of Kasprzyk-Nill-Prince, Lutz, Hacking and
Lai-Zhou. This confirms a deep and surprising structure to the classification
of log del Pezzo surfaces first conjectured in work by Corti et al. In higher
dimensions, I survey the evidence from the Fanosearch program, cluster
structures for Grassmannians and flag varieties, and moduli spaces of conformal
blocks. The paper is submitted for publication in a volume on the occasion of
the 70th anniversary of V. V. Shokurov.
