| Discovering what the video is about as it discursively unfolds

| (multiple moments, even) where you'll suddenly be like, "wait,
| I can't believe what you appear to be suggesting", only to find
| out that not only is he suggesting it, he actually implemented
| it. There are few video creators who are as attuned to the
| hacker mindset as Tom7; I decline to summarize and instead

| a video about the logistics of juggling a trillion chainsaws,
