Interesting. Would you, when interviewing a 30-something fresh out of Etsy, assume they were unlikely to be a 'boring technology' advocate?
Because 'Choose Boring Technology' was originally an essay/talk given by Dan McKinley[1] describing the lessons he had learned at Etsy, which he left in 2014, approximately 12 years into his career. His strongest motivating example of a case where he 'chose boring technology' is a system his team built in 2010, when he would have been, I think, around 30. Is that 'a certain age'?
