I believe that deep, down its a question of identity and incentives. The right thing to do is reduce complexity.

But the thing that optimizes for nerd status and job security and resume building is to increase complexity, because most people cannot appreciate the sophistication of simplicity in some technological niche, and it is not easily communicated.

And then there is the question of what gives you joy? I find that for most coders, their primary motivation is not to solve a customer problem in the quickest, simplest and most efficient way, but to challenge themselves with riddles and learn new tech and follow fashion. This definitely varies by culture - Golang and Haskell are on opposite ends in that spectrum.

Overcoming delusion means to exit one's own mind and observe the real world. Looking at useful and well-made software, in which language is it implemented in? A Haskell fan will have no trouble talking for hours about how its concepts are superior. But he will not notice that there is barely any popular software written in Haskell out there, and he will not understand what that implies.
