To mitigate the risk of misuse, some pundits and policymakers propose requiring hardware “kill switches” or built-in controls that can remotely disable GPUs without user knowledge and consent. Some suspect they might already exist. NVIDIA GPUs do not and should not have kill switches and backdoors.
Sounds nice, especially considering how they tried to limit consumer-grade GPU ability to mine cryptocurrency. It may have been a noble effort, but it was both futile and anti-consumer.
