After recalling that the sharpened version of the WGC proposed by Ooguri and Vafa implies that any stable non-SUSY AdS vacuum is in the swampland, we will present several consequences that this may have for the SM and some of its extensions. First, we will argue why it is interesting to consider compatifications of the SM to 2D on $T^2/Z_N$. From these we can conclude that the SM is not robust against the appearance of AdS vacua in 2D and hence would be, by itself, inconsistent with quantum gravity. However, if the SM is embedded at some scale into a supersymmetric version, these AdS vacua present in the non-SUSY case disappear or become unstable, suggesting that the WGC favors supersymmetry. Finally, we present different scenarios in which embedding the orbifold action into different gauge symmetries can lead to additional constraints.
