> Simple-minded, care-free near-incompetence can be better than industrial-strength good intentions paving a superhighway to hell. The "real world" outside the computer is full of such examples.

Overengineering is insidious - "It is difficult to get a man to understand something, when his salary depends upon his not understanding it". A team can sell a solution better than a single person fixing something without making a big deal out of it. You get organizational clout and inertia on your side when you make something big and expensive.

And then complex systems are by nature hard to reason about and by extension hard to critique.

So many things come down to "complexity is the enemy".
