Cool tour.
I haven't kept up with their developments; what kind of workloads have they been pushing for? Since they don't seem to have any specialized accelerators in the Compute Sled, I am assuming they are not targeting AI workloads for now?
NVIDIA has one primary weakness here: GPUs are NOT optimal hardware for training or inference. No competitor has the market reach to challenge them though. An open standard supported by high growth, breakout startup would change that though.
