Ban ultra-high-bandwidth interconnects, not GPUs, to stop large-scale AI training
davidmanheim · x · 2026-09-24
David Manheim proposes that restricting large-scale AI training doesn't require banning GPUs. Since at-scale training hinges on reduced communication overhead, banning ultra-high-bandwidth interconnects and NICs supporting GPU-only RoCE communication would permit inference while blocking frontier-scale training — a more precise lever for compute governance.
