Your summary seems to miss a later quote from the article:

> Extropic is also building semiconductor devices that operate at room temperature to extend our reach to a larger market. These devices trade the Josephson junction for the transistor. Doing so sacrifices some energy efficiency compared to superconducting devices. In exchange, it allows one to build them using standard manufacturing processes and supply chains, unlocking massive scale.

So, their mass-market device is going to be based on transistors.

The actual article read like a weird mesh of techno-babble and startup-evangelism to me. I can't judge if what they are suggesting is vaporware or hyperbole. This is one of those cases where they are either way ahead of my own thinking or they are trying to bamboozle me with jargon.

I personally find it hard to categorize a lot of AI hype into "worth actually looking into" vs. "total waste of time". The best I can do in this case is suspend my judgement and if they come up again with something more substantive than a rambling post then I can always readjust.

Am I the only one who thought the article was clear, lucid, and reasonably concise?

The company's success or failure will depend on execution, but the value proposition is quite sound. Maybe I've just spent too much time in the intersection between information theory, thermodynamics, and signal processing...

"Don't splurge on high SNR ('digital') hardware just to re-introduce noise later." == "Don't dig a hole and fill it in again. You waste energy twice!"

In most applications superconductivity does not actually yield better energy efficiency at system level, since it turns out cooling stuff to negative several hundred degrees is quite energy demanding.
