Software development has a long and infamous history of The One True Way to Write Code(tm). Object oriented, agile, dynamic typing, and TDD have all had their moments where it was "known" that it is the only way to efficiently create quality, maintainable software. All of them have their place, but none have managed to maintain the level of importance their evangelists promoted. I often wondered why software development is so prone to evangelical thinking. There are important lessons to learn from the hype, but my experience is people become more concerned about the religious practice than the actual software.1. TDD is simply the latest. And, like the others, TDD will have a long lasting impact on software development. Eventually, reasonable testing will be part of the collective software culture (it getting closer, but not quite there), and tests will be written for most projects.

"TDD doesn create design. You do."Sorry, but this is akin the fallacious "guns don kill people" argument.
but this is akin the fallacious
But whatever the overall argument, TDD certainly changes how things are designed, and what kinds of things are easy or difficult to achieve. I come across every single one of the ones he mentioned.
First, let me say I agree with you. Even people who should know better say "I not saying TDD is the only way, but if you don do it, show me what you use that is as good". (I looking at you, Uncle Bob). This has the unstated assumption that TDD is the best tool available, Air Max Shoes Yellow

TDD. If we instead demote TDD from its priviledged place to "one methodology, not formally proven, that may or may not work for you", I presume the backlash will go away. And so will the people who tell you that if you not doing TDD, you doing development wrong.
A more interesting question is whether or not TDD leads to better design or not. Even if TDD doesn change the difficult of good design, it can empirically affect the level of design. Here a theoretical example of how that possible: changing the design before tests are written and without using TDD requires less time than when using TDD. The reason (hypothetically) is simple: you need to rewrite tests more if you using TDD. TDD is a methodology, a way of doing things. It a tool it can change things without human input. TDD does not change design; it can It only amplifies a person ability to do that by making poor abstractions and weak boundaries clear and that is the power of it as a methodology.

"A reasonable way to develop a mathematical function like Fibonacci is to use TDD" (I never can get if the person writing this knows that not Air Max 95 Chili Red the case but forgets to explain it, or if they truly believe that. But TDD zealots (again, not talking about commenters on HN, but TDD well known evangelists) will make you feel bad if you doubt a single one.
