Ethereum co-founder Vitalik Buterin suggests a temporary "pause" on global computing power to mitigate risks from potentially harmful AI superintelligence. In a recent blog post, Buterin warns that superintelligent AI could emerge within five years, with unpredictable consequences. He proposes reducing industrial-scale compute power by up to 99% for 1-2 years to give humanity time to prepare. This "soft pause" would only be considered if liability rules prove insufficient. Buterin's idea contrasts with unrestricted tech development, advocating for a cautious approach to AI advancements.
