Had to double-check the date on that article to make sure not a late April Fool's thing. Robots made of iron oxide? Which is, essentially, rust? Nope nope nope nope, who wants that in beer? And anyone who has a clear fermenter knows that yeast swim around plenty, although it's not really swimming but being propelled by co2 farts. This sounds suss to me. Also couldn't read the whole article because I don't want to subscribe to that.
