alt Hacker NewsSorry, I was not quite saying my fun was the reason, but that the failure to create something GPU/ASIC resilient was the more general underlying cause.
But be careful about "proven" in that last sentence - the absence of a solution isn't exactly proof, it's more of a proof that _either_ it is possible to create an ASIC-resistant algo _or_ it has not been worthwhile to ASIC-ify it given the economics of mining XMR and the research & NRE required to do so. I haven't the foggiest which of those two it is, mind you, just that there are a few remaining valid explanations.
It's a proof that something is possible to show one example.
In this case the claim was ASIC-resistant PoW is possible, and the proof has been the historical behavior of miners after years of RandomX. Nobody said it would be eternally or entirely resistant to optimizations...
