My problem is with such articles that very rarely I see some in-depth argument with numbers and details to justify the switch. Many engineers are just too lazy to drill down and get to know their stack so that they can scale it up when necessary or add/remove fetaure, fix bugs with reliable veolicty. I have spent some time in California working for startups and the ratio of engineers who know their stack in depth to ones who would switch language because of trends, never really get to know anything in depth is 1:100.
