The most famous slogan of the Swampland program is that not all effective field theories (EFTs) admit ultraviolet completion into quantum gravity. In this talk, we focus on the significance of this claim for EFTs which involve scalar field variations and on the implications for cosmology. To conclude, we examine some concrete string-phenomenological set-ups with warped throats. [please email a.held@imperial.ac.uk for zoom link or password]
