Computer science enrollments fell across University of California campuses this fall, marking the first systemwide decline since the dot‑com crash, according to reporting cited by University Business. The drop—about 6% systemwide after a 3% decline the prior year—suggests students are shifting away from traditional CS majors, even as demand for AI-focused programs rises. UC San Diego was the notable exception, having launched a dedicated AI major that attracted new students. The pattern raises questions for program planning, faculty hiring, and capacity decisions as universities balance legacy CS curricula with rapidly evolving AI specializations and labor-market signals.
