See I think the only *real* change modernity has made here is we began expecting experts in, say, Ancient Roman horticulture, to be useful generally. Like... no, they told you EXACTLY what their expertise is in my dudes and it ain't practical decisionmaking nor public policy, &c.
something people don't understand about academia is modern professors are so hyper specialized that they're more like technicians than scholars
they're no better at reflecting on life and society than your car mechanic
