I didn't say that, at all. But it is an extreme form of abstract complexity which is different to the more tangible and physical complexity that you might have in say a jet engine. That is not to say a jet engine isn't complex, it is and obviously so; but in many ways I think most people don't fully understand the extreme complexity of a medium to large software project because, on the surface, we've apparently captured a lot of it behind reusable libraries and the like. The reality is much more nuanced due to the fact that most software engineering is not following a technique of provably sound composition of components and therefore complexity emerges and is a sum of its parts. That summing of complexity creeps up on a development team and emerges as bugs, security issues, difficulty in planning, and difficulty in maintenance, etc.

My singular argument is: reduce complexity, improve predictability.

> But still, estimates can't be avoided.

I also didn't state that estimates can be avoided. I ran a tech company for 20 years and I needed to be able to tell everyone else in the company when things are likely to be done. That's just a fact of life.
