In the film *Leave the World Behind*, Tesla vehicles crash into one another. The cars speed forward, slamming into the vehicle ahead before finally stopping. Another car then charges forward with a deafening roar. What they all have in common is that every driver's seat is empty — a scene suggesting what could happen if autonomous driving systems are hacked and vehicles begin operating on their own.
In a manufacturing plant, humanoid robots suddenly stop their tasks and attack human workers. Some robots mistake people for objects to be processed. Control room staff try to rein in the malfunctioning robots, but their commands have no effect. The control system has been hacked by a quantum computer. Faced with robots possessing physical strength, humans are left completely defenseless.
These may seem like scenarios confined to movies and imagination, but they could very well happen in reality. Artificial intelligence agents and physical AI are rapidly entering everyday life. If security systems are breached, the damage could extend far beyond the digital realm into the physical world. As quantum computing technology advances, experts warn that existing cryptographic systems could be rendered useless. Specialists agree that now — as AI transformation (AX) and robotics transformation (RX) dominate the conversation — is the time to prepare with next-generation security technologies such as post-quantum cryptography (PQC).
