Likely they wouldn’t listen. Modern languages and environments seem intent on reinventing bad solutions to solved problems. I get it if it’s a bunch of kids that have never seen anything better but there is no excuse these days not to have at least a passing knowledge of older systems if you’ve been around a while.
there's certainly a piece of it. Also most seasoned people are not very interested in new languages and environments, and most languages are not 'spec built' by experts like Rob Pike building Go who explicitly set out to solve a lot of his problems, but are more naturally grown and born.
