David Sacks says the White House AI safety pledge is a better route than waiting years for an international agreement. He made that argument in his own X post on September 29, after the signing.
Sacks welcomes the participating companies accepting responsibility for safe product development and pledging internal controls and external audits. He says he attended the signing.
His comparison with international negotiations is a political judgment: he doubts such an agreement would happen at all. The post announces neither an end to talks nor an additional binding rule.
AI Incidents records his own position as a risk signal, separately from the joint company pledge already documented. His endorsement does not establish that the promised controls have been implemented or work effectively. It does not report a new autonomous AI incident.
