Detecting a stochastic gravitational-wave background with LIGO/Virgo/KAGRA: are we there yet?

In a recent review paper, we outline what constitutes a GW stochastic background, and give an overview of stochastic detection methods with different GW experiments. In this talk, I will focus on detection methods with the current second generation interferometer network, laying out a roadmap to detection. In the process, I will characterize the GW background we expect to measure with the 2G network, and highlight the challenges we face when trying to measure this elusive signal.
