Nope. Something of the sort was said by someone on the Halo 4 panel at Halofest. It went something like "When humanity's not being rocked back on their heels, they're actually a pretty formidable race. There's been a lull in the fighting for about 3 years now, humanity has the ability and time to study forerunner artifacts and learn from them."
It's not the exact quote, but it's a close approximation. This hints to humanity at least having a partial understanding of how to work forerunner devices and whatnot. I wouldn't be suprised if Halo 4 introduced some forerunner weapons other than the sentinal beam. Possibly a forerunner midrange weapon not unlike a beam version of the BR. Instead of a short bust, there would be a single "pulse" of (probably) blue energy. Think DMR fused with a sentinal beam.
