  Recently, an infinite class of holographic generalized complexities was
proposed. These gravitational observables display the behavior required to be
duals of complexity, in particular, linear growth at late times and switchback
effect. In this work, we aim to understand generalized complexities in the
framework of Lorentzian threads. We reformulate the problem in terms of thread
distributions and measures and present a program to calculate the infinite
family of codimension-one observables. We also outline a path to understand,
using threads, the more subtle case of codimension-zero observables.
