The article argues that a good tool should be invisible, meaning it should not require a lot of effort or attention to use, and that many people mistakenly celebrate the flaws of their tools as a fun challenge. The author uses the example of text editors, such as Vim and Sublime, to illustrate this point. They suggest that a good tool should have good defaults and allow for easy customization, rather than requiring users to spend a lot of time configuring it. The author also discusses how some people's identity becomes tied to their tool of choice, leading them to defend its flaws.
