As a hardware founder, low quality plastic is not rocket science. On trips to China I’ve heard similar things about other companies, specifically that Foxconn makes everything it uses, including things like coolant or plastic for prototype production.
Does anyone know what their chips are doing? Do you, really?
Until we have desk side silicon fabrication/placement, with accompanying tunnelling microscope features, we simply cannot trust our silicon in any way other than through utterly peaceful means, which is to say, through systems of human trustworthiness.
Technology never allows us humans to advance sufficiently well to do without it .. unless it is evenly distributed.
Right now we are all at the mercy of the masters of silicon. This is no joke!
So, the plastic bits?
