So.
1. “Every programmer” is a matter of speaking. Obviously not every programer should try any of. Author I believe knows that.
2. If you are not a programmer you don’t add to the list. Period. You wouldn’t be adding to the list of “drills any dentist should try”, right? So why here?
3. If you are a programmer, and have not tried all of the above why are you adding more? Yah, I know, you once did a challenging project that is not on the list. So did I. “Doesn’t make me Madonna, never will”.
Now what if you are a programmer and you’ve done all on the list, with or without substitution (like Snake might be equal Space Invaders)?
In which case you’d have at least 6 repos to share with the world, and if you can implement Tic-tac-toe live, you might get to the next round of interviews.
