These charming 15" long worms with copper reinforced jaws are effectively in the Bronze Age. Soon they will transition to Iron, then they'll probably bypass the Industrial Age as too polluted (might as well learn from other's mistakes) and besides a coal fired worm is a pretty odd worm, and go full on nuclear. Worms with frikking lasers is what we will soon be contending with. Oh actually they are far more interesting than that: "The worms turn their digestive system inside-out and launch an appendage, called an eversible proboscis, at their prey." ... and they are venomous. So you approach your adversary. They turn around and drop their drawers and then it gets really weird. They extrude their entire large intestine through their arse and the end of it is sporting four metal fangs and dripping with poison.

How about an iron age snail? It lives near deep sea vents and uses iron minerals in its shell and scales on its foot. It also has symbiotic bacteria in its gut so it doesn't feed directly. https://morethanadodo.com/2015/04/28/the-iron-snail/ https://morethanadodo.com/2015/04/28/the-iron-snail/

  Iron sulfide is an unrefined ore that humans could access well before the iron age (if or when they ever had a use for it). Fortunately for the birds (and fish with the ecological role of birds) of the world, there are no truly iron snails.

They will skip the industrial age, evolve fusion generators as stomachs, and be impervious to deep space. Launching themselves into the universe with large trebuchets and fusion fart themselves into orbit.

  They'll live in the Gobi and Sahara as the size of whales as well. Their advanced biochemical processes will shape the ecosystem around them and spread the deserts further. A byproduct of their chemical processes will be a panacea for mental acuity and aging come to be know as melange. People will worship the giant worms and call them "the maker."

> Soon they will transition to Iron Iron is strong, but not that hard and would wear away quickly. Tooth enamel is actually harder than steel and very wear resistant. Iron compounds like hematite are harder, but more brittle. Iron is a pretty common element, I suspect if there was an iron compound better than calcium compounds for teeth we’d already have iron teeth.

  Tooth enamel is not as hard as even unhardened steel. It's a composite material whose hard phase is hydroxyapatite, a hydroxyphosphate of calcium, which is even more brittle than hematite. But the hydroxyapatite crystals are below the critical size for flaw-insensitivity, and the protein matrix that binds them together is too soft to propagate cracks from one to the other. Limpets' teeth do use goethite, an oxyhydroxide of iron, in exactly the same way, achieving hardnesses that do exceed iron's. So in a way we do already have iron teeth because there's an iron compound better than calcium compounds for teeth, if "we" includes mollusks.

  "Iron is strong, but not that hard and would wear away quickly." I was simply making a bit of a joke about progress. Why is the bronze age not called the copper age and why is the iron age not called the steel age? "Tooth enamel is actually harder than steel and very wear resistant." Really? In which case I would like you to take a bite out of any RSJ you care to choose. That's a rolled steel joist which are not hardened but designed to work well as beams. Material properties are quite tricky. Hard really means errr hard: a diamond is hard - it can scratch glass. Glass is hard, most steels can't scratch glass. Steel is generally not that hard but can be depending on the alloy (mixture with other elements/etc) Then there are the other material properties such as stiffness, ductility and elasticity and the rest. Iron is generally brittle so if you make a sword out of just iron it will be quite stiff and look lovely until your opponent smacks it and it breaks. I can give you a load of steels with loads of different properties depending on what you need. The difference between iron on its own and steel is amazing. Pop in a bit of chromium and it resists rusting, for example. Steel is much more than just adding carbon. Please don't bite any of them - they will destroy your teeth.

At what point will the worms start the Internet and use phone apps for home delivery? There’ll be a demand for 4G connections; that’s a YCombinator business opportunity waiting to happen, looking ahead to see future demand. worm -> whorm-> whorm’st -> whormst’d

Actually this is not so. The worms extrude their pharynx, i.e. the anterior part of their digestive tube, through their mouth and catch the prey, and then they pull the prey in their mouth, like some of the alien monsters from various SF movies (which were obviously inspired by such worms). Catching a prey from behind does not seem to be of much use, because the prey would not be chasing the predator. For a worm, which normally slides through narrow passages or which burrows in the sand, it is not easy to turn around with the rear end towards what was previously in front.
