> This is an absolutely disingenuous point that compares the cost of full-economy-of-scale tech to literal one off R&D prototypes.

No, even at scale, materials that you can extract from ore are inherently going to be cheaper than materials you have to extract from three different ores and then crystallize, even in a manufacturing lab. These just aren't comparable processes, and no amount of scale is ever going to fix that.

Instead of assuming I'm making a disingenuous point, you might have asked for clarification.

That's setting aside the problems others have brought up, which is that the materials in question have other properties besides conductivity which make these materials inappropriate for transmission application.
