And it is not like making a copy for cheaper isn't something that requires skill and innovation. Or then iterate on that copy. Didn't Roomba just fail to these copies. If west was truly so much more innovative and better shouldn't they as company be infinitely ahead still?

I never said that, or that there's something wrong with copying. I just said the sentence implies copying. Which it does.

And in fact this meme Chinese only copy is crap as I point out in my last paragraph. Over the centuries the Chinese were the first at quite a few things.

But the sentence says what it says.
