If you feel microdots are obvious, how often in the past have you talked about them? Can I find something on your comment history where you bring it up? Are there Hacker News threads or news articles where it has been discussed before now? And I don't just mean buried in the 11th paragraph of a single article. I mean examples of conversations that show it's pervasive enough that it rises to the level of "obvious" that people are insisting it is.
