We present a novel extraction of the pole position of the f0(980) from the available dispersive analyses of the $\pi\pi\to\pi\pi, \bar{K}K$ channels using an effective range expansion. Afterwards, we use a neural network as a classifier to investigate the possible nature of the state, finding that a molecular interpretation is the most likely.
