No idea is it is state of the art but I just tested PimEyes(the reverse image search service mentioned) with an old photo of me, it returned a bunch of photos of random people but also two of me within the first 30-40 results. One is older, 7-8 years maybe, and one is more recent, 2 years perhaps. I have different facial expressions and the pose/angle is different than the one I submitted.
