ultra pure water production itself is responsible for untold amounts of hydroflouric acid and ammonia , and most etching processes have an F-Gas involved, and most plants that do this work have tremendously high energy (power) costs due to stability needs/hvac.
it's not 'just sand'.
How would you suggest doing it with fewer materials?
The claim was that "the materials that go into a chip are nothing". Arguing that that is not that case does not really put someone on the hook to explain or even have any clue how to do it better.
