> There are a lot of “Experts” out there, who know node.js, Java, or just Spring Boot, Numpy, and so on. But this is not development. This is playing Bricks with predefined methods and classes. I work in the finance sector and a lot of these things I create could perform better on less big hardware.

I agree, with this, and the general sentiments in this blog post.

Yet I am one of those "Experts" out there who knows nodejs et al, and builds things with it. I recognise it's deep flaws, evade them as much as I am able and am always trying to find better ways of doing things - but this is the domain I work in, and using these tools and building blocks to some degree is quite difficult to completely avoid (and I say this as someone who has gone to quite some extremes in my attempts to do so).

My point is, even though the issue is a cultural one, not everyone caught up in a particular manifestation of these issues is blind to them - Please remember this the next time you judge a web dev, or foo dev, or someone from whatever area you perceive to be hopelessly flawed.
