Saw the title and thought "oh, I'll bet it is at some insane high pressure or some other exotic condition". Clicked through to an image of a diamond anvil. Not disappointed.
It's so annoying to read science articles about how X will revolutionize Y, but you have to dig through the comments section to find out why it won't work.
Most new research findings only have very specific applications. It's only groundbreaking when something can (eventually) be implemented in real life for a reasonable cost.
And yes, I say misleading. Technically true but misleading, because their omission is absolutely critical to the nature of their breakthrough and as you implied, anyone who knows the first thing about room temperature superconductors will want to know if the material has a drawback stopping it from functioning outside of a strictly lab setting.
