I think college's value proposition and entire model has been eroded. Major school's CS grads are finding jobs upon graduation at an 11% rate (I don't have the primary source on this, but it is published by a site I read that never fudges these kinds of things, going back many years). AI probably has a lot to do with that, but it's exposing something more fundamental. CS wasn't supposed to be a programming boot camp…
One example from 1985 onwards that i can think of is NSF funding of supercomputer centers. 40 years ago, SIMD / vector processors with boatloads of memory were not ubiquitous, nor were shared memory multicore / multiprocessors, a situation which differs with the reality today.
This NSF funding established the 5 supercomputing centers

and then further downstream effects include popular access to creations from the supercomputer centers, such as Mosaic from NCSA, and an expansion of ideas outside the compuserve / aol paradigms.
I think similar situations apply for other engineering disciplines, mechanical and chemical and physics and so on. Probably true for the arts in various forms: people don't have personal pipe organs to learn Bach on, for a crazy example, but universities do.
For various industries, learning requires physical equipment too expensive for individuals, historically and still.
