In the long run, that will be the workers' (and perhaps society's) problem, not the manufacturers'. If manufacturing requires fewer workers, either existing manufacturers will shed staff or new, leaner, upstarts will sell an equivalent product at lower cost.

I don't think electric = more unemployed.

Or rather it's more likely that they're just taking the big switch as a chance to redesign everything. Incl production processes.

That would have happened by next cycle anyway in my view. Electric merely hastened it a bit.
