Reminds me of Silvino, the Mexican ultra marathoner, who ran using slippers and who couldn't understand the Americans who started running on slippers because they thought it was good for them because the locals/indigenous people ran like that. Silvino asked why are they doing that to themselves. Why are they suffering voluntarily. LOL.

So why are these professors going back from progress, from the best/better way of doing things? If they're going to change, it should be going forward, and not backward.
