I'll discuss the philosophy of relating categorifications using deformation and localization. While this can be applied in a number of settings, I'll focus on recent work which gives a categorification of iQuantum groups in the style of Khovanov and Lauda in many cases (which includes a new proof of the non-degeneracy of the original categorified quantum groups as a special case). This is joint work with Jon Brundan and Weiqiang Wang.
