AI can potentially threaten Bitcoin's decentralization if attackers use it to attack the network or manipulate it. For example, AI is able to optimize a 51% attack by analyzing network weaknesses, or create complex botnets to influence consensus.

However, the Bitcoin architecture itself is stable: PoW makes it more difficult to concentrate power, and open source allows for quick adaptation. As long as AI does not control physical resources (energy, equipment), radical threats are unlikely.
