Superfluid turbulence is a unique system in which the laws of classical physics gradually transform into the quantum laws along the energy cascade from large to small turbulent scales. The current picture accetped by most experts in the area, is that system behaves like classical Kolmogorov turbulence whereas at the small scales it takes form of Kelvin waves on quantised vortex lines. However, little can be said with confidence about the crossover range. I will describe recent predictions for the cross-over range, as well as the ongoing controversy about these predictions and about the small-scale spectrum.
