Do you believe that IS-LM still has a place in the profession?

Please provide comments on the attached article.
Many people have strong opinions on Paul Krugman since he regularly writes articles in the popular press including strong political opinions. This article, however, is really about the state of macroeconomics. He wrote this article a long time ago, but more recently he has written similar articles and given speeches with essentially the same subject matter as discussed here.
Despite the fact that most newly minted Ph.D economists have genereally abandoned IS-LM, the older generation of economists, including folks like Krugman, Bernanke, and Yellen, grew up on IS-LM, so it is part of their analytical tool kit. Also, Mankiw's undergraduate macroeconomics textbook, which is the most widely used macro textbook out there, features the IS-LM model. So, to this day, the IS-LM model remains the most commonly taught macro model to undergraduates.
Do you believe that IS-LM still have a place in the profession, or is it now time to drop it altogether? I struggle with this question, as for this course, sometimes I include it and other times exclude it. You will notice that the author of our text, Williamson, has decided to drop it (earlier versions of the text includes IS-LM).
Your objective should be to understand the ‘main objectives’ or ‘takeaways’ of the article.
