TSMC executive cautions on AI's current capabilities for chip manufacturing

Y.J. Mii, TSMC's co-chief operating officer, warned that artificial intelligence, while powerful, remains immature in its development and poses security risks that warrant caution. In remarks captured by Bloomberg on September 16, Mii compared AI to a toddler with extraordinary powers lacking judgment about right and wrong, and cautioned that improper deployment could expose confidential data. He specifically noted that AI currently offers limited value in developing the most advanced chipmaking processes—a significant statement for a foundry leader whose strategy depends heavily on process technology leadership.
