Except the nature of work has ALREADY changed. You don't study for one specific job if you know what's good for you. You study to start building an understanding of a technical field. The grand parent was going for a mix of mechanical engineering and sales (human understanding). If in mechanical engineering, they avoided "learning how to use SolidWorks" and instead went for the general principles of materials and motion systems with a bit of SolidWorks along the way, then they are well on their way with portable, foundation, long term useful stuff they can carry from job to job, and from employer to employer, into self-employment too, from career to next career. The nature of work has already changed in that nobody should study one specific tool anymore and nobody should expect their first employer or even technical field to last more than 2-6 years. It might but probably not.
We do need people who understand how the world works. Tall order. That's for much later and senior in a career. For school purposes we are happy with people who are starting their understanding of how their field works.
Aren't we agreeing?
