I wonder whether they ever will be. Our ability to peer back in time relies entirely on what we can see and the radiation we can capture and analyze. Looking back far enough, it all becomes opaque because "first light" hadn't happened yet. Perhaps some new tech will throw the doors open some day, but if we cannot see past a certain point, and that point happened after the "bang," then we will never know what came before the opaqueness.
For that reason, I don't know for sure that the singularity has any merit. If we run the clock backwards we get a singularity, but since we can't see past a certain point, we don't actually know whether singularity is a real concept.

It’s not just about looking “out there”, a lot of the early-universe physics are probed in high energy particle colliders. It’s mostly about understanding quantum effects at that point.
