I haven't yet read the full blog post but so far my response is you can have this good parallel computer. See my previous HN comments the past months on building an M4 Mac mini supercomputer.

For example reverse engineering the Apple M3 Ultra GPU and Neural Engine instruction set and IOMMU and pages tables that prevent you from programming all processor cores in the chip (146 cores to over ten thousand depending on how you delineate what a core is) and making your own Abstract Syntax Tree to assembly compiler for these undocumented cores will unleash at least 50 trillion operations per second. I still have to benchmark this chip and make the roofline graphs for the M4 to be sure, it might be more.
