The author is surely big fan of performance (or anti-fan of Python? ). Spending half of the post attacking performance without mentioning the task being done feels very much like those old "let's write this web forum in Assembly language FOR SPEED" forum posts. Later on, author goes and says "At the highest level, tool choice decisions are complicated." and "You can write something similar about any useful technology" - but that does not really work with the first half of the post being very simplistic and one-sided. (Note this might work much better with some context. There are some projects where speed really matters, like high-performance message server, but there are no context-setting markers in this post, it is written in general tone)
