The tech industry is significantly larger now than it was a decade ago. Large self-sufficient talent pools of SWEs, Designers, PMs, PMMs, and SEs/AEs exist for most subsegments of tech now.

Additionally, limiting early career hiring to to T10/20 CE/CS/ECE/EECS programs (they tend to graduate around 10K students a year), veterans (they tend to have the "can-do" and fast learning mindset needed), and a couple regional schools is more than enough to build a self-sustaining early career pipeline for just about any segment of tech indefinitely.
