But Infiniband didn't do that.

you can do point-to-point connections with infiniband, it's a pretty common homelab use-case since adapters are so cheap these days.

InfiniBand is always point-to-point, that's the point. The talk about "bus" is confusing/wrong since it never is a bus.

oh, "bus" in the context of an actual bus, like CAN. I thought p2p just meaning direct-attach. But yeah it's switched, it's not a shared bus.
