Sometimes you'd think so. It's actually more delayed than you'd think; major celebrities are often several minutes between major article publication and edit, when theoretically you could speedrun that kind of edit with a source in about two minutes from time of reading the article.

You might've seen this, but the editor who changed Henry Kissinger to "was" became such a social media phenomenon that day that her talk page was flooded with "congratulations". An administrator (being responsible, tbf) had to step in and remove gravedancing, my own included.

Shame this kind of edit isn't consistent or "Was%" would be a really fun speedrun. "Banned from Club Penguin%" energy.
