He's missing the bigger picture, IMHO. Nobody goes back to fundamentals because the industry is not allowing the role to do that. FE engineers don't have control over the codebase to this degree, and the expectation from the company is more about business profit, more usage, etc., instead of building something that will not need to be rewritten.

In other words, the article misses the huge factor that companies don't care enough to allow FE engineering to be about building things properly, and instead make it something akin to a product owner with technical skills.
