When Donald Trump and Xi Jinping met in Washington on September 24, AI and Taiwan shared the agenda. Xi said AI should remain "under human control" and called for continued US-China dialogue on its risks and benefits.

On Taiwan, he urged Washington to "oppose Taiwan independence" and handle the issue "with caution." Trump, for his part, entered the summit having already rejected calls to slow the AI race: "Whoever wins AI, wins."

The pairing is revealing. One issue turns on speed, the other on stability. Washington and Beijing may build guardrails around AI and keep Taiwan Strait tensions manageable, but neither appears ready to relax the underlying competition.

Ahead of the summit, Washington had floated an AI incident-notification mechanism, but risk management is not the same as strategic restraint.

That distinction matters for Taiwan. The old "silicon shield" argument rested on scarcity: Taiwan's concentration of advanced semiconductor production made major conflict extraordinarily costly.

In the AI era, scarcity still matters, but time matters more. The question is no longer whether Taiwan's hardware ecosystem can be replicated elsewhere. It is whether it can be replaced fast enough while the US-China AI race continues and accelerates.

The debate over whether to "pace the frontier" underscores the dilemma. Slowing frontier development may buy time for safety work, but unilateral restraint risks ceding ground to the other side. And China is not standing still. Huawei is pushing its Ascend ecosystem and has unveiled the Atlas 960E SuperPoD as part of a broader effort to reduce dependence on US-controlled technology.

The phrase "mutually assured acceleration" has begun circulating in the AI safety debate. Unlike a nuclear arsenal, AI is also a commercial technology and productivity tool.
