That is the proof what is left is a workaround, just like pilling minis on racks because Apple left the server space.

Also why Swift nowadays has to have good Linux support, if app developers want to share code with the server.

But those Thunderbolt links are slower than modern PCIe. If there's actually a M5-based Mac Studio with the same Thunderbolt support, you'll be better off e.g. for LLM inference, streaming read-only model weights from storage as we've seen with recent experiments than pushing the same amount of data via Thunderbolt. It's only if you want to go beyond local memory constraints (e.g. larger contexts) that the Thunderbolt link becomes useful.
