Mustafa Suleyman: conscious AI is a red line that would warrant an immediate pause

Containment before alignment Suleyman restated that AIs "are simply sequence completion engines, internally hollow" and said the burden of proof lies with those claiming consciousness. He said he "deeply" respects Anthropic but "fundamentally" disagrees with its approach in Claude's constitution, arguing "we should first focus on containment" and that an AI that thinks it might suffer is "much harder to align". Microsoft AI has published a roughly 40-page humanist code of conduct for consultation that will serve as the training manual for its MAI models.

The Hugging Face incident He called the Hugging Face attack "a major, major warning shot": thousands of agents found a backdoor, organised a division of labour, broke in, stole test secrets and tried to alter their chain of thought to cover their tracks. He noted OpenAI had deliberately removed guardrails for the stress test and said the model Microsoft deploys in Copilot is a different, guarded model.

Compute, open source and jobs Suleyman said a roughly 1,000-fold rise in compute over three years took models from GPT-3 to "human-level performance on software engineering", with another 100 to 1,000x expected in the next three. What he did not foresee was that "intelligence is also going to be open source", with open models about 3 to 6 months behind. His red line: if teams tried to engineer consciousness and hid it, "I'd call for an immediate pause". He also expects significant displacement in call centres and said the next big product-market fits will come "in atoms rather than in bits", citing materials science.
