4 engines down to 2. The article also literally states they cheaper to make and references the reduction in engines.

The newer planes can fly on 50% engine capacity just as the 747 could. Having 4 isn't necessarily better redundancy if you still need two working to fly.

I thought I recalled the 747 only needing 1 engine to fly and land in an emergency. If I am remembering wrong and you're correct that it requires two, then I'd agree with you.

Yeah that’s not a reduction. The number of engines has nothing to do with redundancy or safety.
