That a technology to develop the spinning wheel should have been around a lot sooner, but it seems to have not appeared until relatively late in the history. Now yes, we are talking probably a thousand years before, but the idea is simple enough that you would think that the ancients who knew all the different pieces such as the lathe could have made that work.
Spinning Jenny? Yeah, that's complex enough that it couldn't have appeared much sooner. I'm not sure if the cotton gin would have been possible sooner or not.
But have you heard anyone _talk_ about it? It's common knowledge that the industrial revolution was mills and steam engines and mechanization. In my experience almost no one knows about the other piece of the textile industry that drove industrialization.
It's not hidden, but I don't think it's commonly known.
But yeah, that entire IG Farben episode might have toned down their enthusiasm for identifying with dyes a little. Same for their peers up and down the Rhine.
