Our best paradigm for physics at high energies gives rise to extremely complex low-energy effective potentials with a large number of light degrees of freedom interacting via non-trivial couplings. This picture is usually referred to as the string landscape and is the reason why building concrete ultra-violet complete models of inflation is so hard. To make progress in this direction, I suggest fully embracing the idea of complexity in the underlying theory. By making use of stochastic tools one can study the implications of complexity for the phenomenology of inflation and attempt to make sharp predictions. In this talk I will present some examples where this approach has been taken and discuss possible ways forwards.
