There was an expression at my school, in response to exactly what you're questioning.
"We train you for the last job you'll ever have, not the first."
The intent of a well-rounded bachelor's education isn't to be able to walk through the JavaScript library du jour from memory, but to have at least a base level of understanding how everything adjacent to the thing you're doing works.

That's a bit funny for Computer Science since, even though I don't have numbers, I expect the average graduate now to work until they're 65+, and the vast majority will probably be out of the field of direct software development by the time they're 45 (burnout, people management, program management, project management, executive suite, etc).
