Sure, but 72x Neoverse V3 (approximately Cortex X3) is a choice that seems more driven by convenience than by any real need for an AI server to have tons of somewhat slow CPU cores.
If someone gave me one for free, I'd totally make it my daily driver. I don't do much AI, but I always wanted to have a machine with lots of puny cores since the Xeon Phi appeared.
The justification is that processors cores aren't getting much faster, but what they are is getting more numerous - entry-level machines have between 4 and 8 cores - and adapting code to run across multiple cores is important if we want to utilise all those cores.
