Well, the elites were worshipping the forerunners for ages. Now they know that the forerunners chose humanity to take up the mantle of protecting the galaxy (they already have...twice at this point...) but the point is, all that forerunner technology, heck, the halo rings themselves...belong to humanity.
It's going to take a couple centuries for the humans to fully pick up on this, but if the elites should be "worshipping" anyone, it should be the humans.
I forsee them getting along eventually.
