Atoms. More specifically, matterenergy concentration in/and spacetime.
They no longer make any, or at least we can't make any for our
own use, though that particular jury is out (to lunch?) yet.

The buck stops at Schwarzschild radius. A whole while before, in fact.
So far, we seem to be stuck with classical computation in cold solid
state. Quite a distance yet to go, but not so many doublings removed.
The only way to beat that would be spacetime engineering, which so far
looks like a complete pipe dream.

We've always been energy limited. We just managed to tap new resources
just in time. We've been aware more than half a century ago, but managed
to drop the ball. Pretty much completely. Now this energy austerity is
going to get pretty painful for a long while.

If we're sufficiently motivated, and not distracted (a nice nuclear
zero-sum resource fight will tend to be rather distracting) we can do
some amazing things.
The question is, do we really want to do them? Not yet, as far as I can see.
Our heads remain firmly lodged in our collective anuses.

I think there are a few million people on the street out there who'd
like to tell you one or two things about the scarcity that is a figment
of their imagination (they'd rather so wish).

We all know how things should look like, but to fund this we need
to rob Peter to pay Paul. A hard sell, since the awareness in how deep
a pile of steaming kaka we've managed to lodge ourselves is still
pretty thin out there.
