I wouldn’t say absolutely, because that would be a flaw in my thinking.
But I am skeptical of the selective use of historical documentation.
They also claim to have proved that this was how the Romans did it, because their experiment achieved a similar result. It didn’t, they only proved they can achieve similar results using this method.
But there is something more I can’t quite put into words yet, that has been bothering me about the way western science and academia think about things.
Side note, this kinda feels like an advertisement for a patentable process they want to sell.
