Well, yes. But that's the general assumption for technical posts, so there's no need to exclaim your specific lack of expertise. (Except perhaps if you are willing to pay serious money to hire said expertise.)

After all, and drawing from recent HN postings, you would need a expert in an certain sort of experimental physics to verify quantum teleportation in 63 miles of optical fiber, and a certain sort of neuroscience expert to verify the decoding of the brain activity of the worm, and yet another type of expert to verify that Enceladus has a global ocean.
