I will revisit Weinberg's constraints on the S-matrix of massless higher-spin particles from the viewpoint of the asymptotic symmetries at null infinity displayed by the corresponding fields. This analysis extends to arbitrary values of the spin the relation between asymptotic symmetries and soft theorems recently explored in gravity, and I will discuss the hints it provides on possible higher-spin extensions of the BMS symmetry.
