When Google published the Nature article, Nature included a rosy intro article by a leading expert in chip design. His name was Andrew Kahng, and he apparently liked Google at the time. But when he dug into Google code (released way after publication), he retracted his intro and co-authored the Cheng et al article. You see how your theory breaks down here.

You are adding information that I did not previously possess. And neither the article nor the previous poster offered.

As I said, the truth will out. I was just unhappy with the case previously being offered.

As Andrew Kahng was one of the co-authors of Cheng et al., all of the issues with his reproduction still matter here. The Nature paper went through an investigation and second round of peer review.

AlphaChip is used to make real chips in production. Google publicly announced its use in multiple generations of TPUs and Axion CPUs, and MediaTek said they've built on it as well.
