Does the universe have a “most basic ingredient” that isn’t information?

From Anil Ananthaswamy at New Scientist:
For more than 300 years we have been asking ourselves about the true nature of reality – what, ultimately, stuff is made of. Time and again, we have found another layer beneath what we thought was the lowest. What’s more, with each new depth we plumb, our old understanding of reality is swept aside.
Now we could be on the cusp of another revolution, thanks to efforts to reconcile our two most successful but incompatible theories of reality. Not particles, energy, space,time or anything else we might think of as fundamental truly is: instead, the essence of reality is a thing whose workings we’re only just beginning to grasp. (paywall) More.
Ananthaswamy may not mean information, which is too bad. If he did mean information, it’s not that we can’t grasp it but that we are unsure how to relate it to matter and energy or how to rule out intelligence as its origin. Not for lack of trying, we may be sure.
