Musk's take of the cut, drivers others to find alternatives.

that just leaves copper. if there existed a room-temperature
flexible superconductor replacement we'd do okay.

We're getting there:

But it'll take a while before production. But the higher the demands on batteries and semiconductors. The harder the search for alternatives.

All semiconductor companies have serious trouble further miniaturizing silicon lithography. If we find ways to reduce resistance in the materials than the miniaturization becomes less of an issue.
