Has anyone looked into this qubic doge mining thing?

I saw that they launched some type of mining setup where old scrypt hardware performs AI training alongside doge mining. They are claiming L3+ miners can be profitable again.

The interesting part is that multiple people are posting actual numbers from their miners that look better than just mining doge.

I am still sceptical about the AI training claims, though. Does Useful proof of work actually work, or is it just a buzz phrase used to justify the story?
