We don't know the current system can work well enough at this scale, because that's un-knowable. We know it can find some of the problems. We don't know it can find all of them.
We do know it takes more effort - that's knowable. Increased data takes increased processing.
Whether the community has the required effort available, seems unlikely, considering the expertise required to be able to assess these things hasn't changed. Only the ability to generate them has increased.
