Does it matter how "tech" is defined? At one point in time, a pencil was considered tech, so when pens were invented, would the same people have said "tech is dead, people aren't interested in making pencils anymore!" Prior to the computer age, tech was aerospace, plastics. Sure the computer age brought a new large kind of tech, and that has been mined, but we are also entering a new phase where sensors are driving new capabilities in health[tech], space[tech] is no longer the domain of a few governments, transportation is being revolutionized [by tech]. With tech everywhere, nobody is going into "tech" they are going to work for companies making things, and those things either are tech or rely on tech. Also, with the value, or lack thereof, that universities are bringing to their students, do we care what industry's those students are going into? And the article doesn't say where they are going, just where they aren't going, so didn't add value.
