A physical interpretation of the two-sheeted space, the most fundamental ingredient of the noncommutative spectral action, proposed by Connes as an approach to unification, is presented. It is shown that the doubling of the algebra is strictly related to dissipation. As a consequence, the doubling of the algebra is intimately related to the gauge structure of the theory. In a regime of completely deterministic dynamics, dissipation seems also to play a key role in the quantization of the theory, following 't Hooft's conjecture. It is thus argued that Connes' classical construction carries implicit in its feature of the doubling of the algebra the seeds of quantization [1].
