The pipeline problem has nothing to do with ability, it's all about the hiring pool and the time it takes to change the hiring pool. Companies can't hire people that don't exist, so focusing solely on hiring practices won't get the desired outcome at anywhere near the speed the activists want (if at all). The activists are focused on completely the wrong area; it's going to take years-to-decades fixing problems much earlier in life before companies would even be able to do such hiring.
