The author makes some good observations but I feel he is undervaluing post-foundation engineering skills. Sometimes the reason why certain companies end up with so many engineers due to the lack of those so-called "10x engineers" -- specifically, those who know how to build robust, scalable systems while coordinating with the needs of product development. I know some of the engineers who have worked for those lean, highly scaled shops and I know for a fact that they know their shit extremely well - and they've poured hundreds of hours into carefully scaling their infrastructure. They could not be replaced by your average full-stack engineer off the street as they'd immediately be in over their head and would have to spend the next few years learning all the hard-won knowledge of the more experienced engineer.
