It is argued that the discovery of cosmic acceleration could have been anticipated on thermodynamic grounds, namely, the generalized second law and the approach to equilibrium at large scale factor. Therefore, the existence of dark energy -or equivalently, some modified gravity theory- should have been expected. In general, cosmological models that satisfy the above criteria show compatibility with observational data.

The Generalized Second Law and the Spatial Curvature Index
Generalized second law on the apparent horizon plus w ≥ -1 and the dominant energy condition rules out hyperbolic spatial sections for homogeneous isotropic universes.
