A coalition of more than 400 prominent scientists and AI leaders, including renowned pioneer Geoffrey Hinton, has issued an urgent call to restrict artificial intelligence models from accessing the internet. The group argues that connecting advanced systems to global networks poses catastrophic risks to humanity by potentially granting them autonomous capabilities and uncontrollable spread. To mitigate these existential threats, the signatories are urging policymakers to enforce strict regulatory boundaries that physically isolate powerful algorithms. This unprecedented warning highlights growing anxieties within the scientific community regarding the rapid, unchecked advancement of artificial intelligence and the critical need for global safety guardrails.
