It is important. We must not forget how to make transformers.

But the knowledge is already being preserved. Unlike the singular army tank plant (which smells like a combination of despair and naphthalene), there are a plurality of transformer factories in the US...and they are always operating at 100%.

As long as that continues to be the case (there's no sign that it will change), then the expertise is actively being employed, refined, remembered, and transferred.

So even if we do nothing, we're good on that front.

We just aren't keeping up with present-day demand. (Hence, the article.)
