It's a fair article with some errors, especially temperatures and the general understanding of how to make the base material steel. For the most part, it's not bad.
I think that a couple fellows would take exception to the idea that wootz cannot be manufactured any longer.

A few of you lucky souls have razor blades made from Alfred's wootz.
Modern damascus is better referred to as pattern welded steel, but damascus, as a name, is common enough even though technically not the most correct term. Wootz, to me, is wootz, nothing else describes it better. But if someone says fulad or bulat, I'll keep up with them and won't blink.
Increasing the layer count of that material either requires cutting and restacking or bending and folding the billet followed by another welding cycle. Japanese techniques are similar but they are primarily cleaning the dross from a bloomed material and not attempting to increase any layer count.
