the way the question was phrased, it was implied that the person thought it had worth. the question was phrased in a skeptical way ... showing skepticism for the worthlessness. showing skepticism that it was worthless. in other words, they seemed skeptical of the idea that it was worthless. so it means the person who asked the question seems to feel like their work has value. which means there is a 99.9% they are right, because they probably know the work pretty well
