The main reason I know for using those switches is when running Chrome headlessly for automated browser tests. I'm sure they have other uses I haven't come across. The fact that the flags are specific to the version of Chrome you are running is not a big deal when you typically specify the version in your test harness anyway.
Mostly focused on the sound that was retrospectively called 'proto-punk' when it emerged in the US (MC5, Stooges, Patti Smith, etc) and Australia (especially Radio Birdman) and elsewhere just before punk.
But it's a sound that you can still hear in many bands today that were born long after that era. Especially in bands like The Hellacopters, etc.
Most of mine are listed here already. Four are worth adding: fusion, for audio, pixelmator, for images, Kitty, the terminal, and Alfred, which is like raycast.
Mostly politics, where I have learned to stop predicting anything that can't be directly seen -- especially the future. For example:
1. Trump wins. I firmly predicted the opposite. To be fair, most polls predicted the same. But the lesson is to be less certain about the future.
2. No chemical weapon found in Iraq. I firmly predicted the opposite. To be fair, when that event unfolded, it was not that long since the world had last seen Iraq actually use chemical weapons against Kurdish insurgents. But the lesson is to be less certain about anything that can't be directly seen.
