Sure, altermagnetism is genuinely interesting: zero net magnetization with spin splitting could enable fast, low-power spintronics, and the other side is right that the physics is exciting. But a new electronics era needs manufacturable materials that work at room temperature and plug into CMOS fabs. Altermagnets are mostly exotic compounds, hard to grow and integrate, and promising lab effects often die at scale. The realistic outcome is niche memory or sensors, not a silicon replacement. Electronics eras are built by fabs, not papers. So call it promising, not era-defining.
