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

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.
