This t-shirt defeated 2 CV model, R-CNN and YOLOv2.
We need better deployed testing suites that can test an adversarial model against many popular classifiers, not just 2.
Even so, the paper itsef shows tht their tshirt doesn't make the wearer undetectable, only partially-undetectable. A security system won't ignore you just because it only saw you 10% of the time you were present (unless it's an Uber self-driving car).
