Why do they need AI at all? Wikipedia had existed long before it and was doing fine.

Why should we use (insert tool) when we did just fine before?

Because when used correctly it can be great for helping you be more productive, and find errors/make improvements. The two exceptions are for grammar which AI does a surprisingly good job with. Would you have gotten mad if they used Grammarly >5 years ago? Having it rewrite an entire article is gonna be a bad idea, but asking it to rephrase a sentence, or check your phrasing for potential issues is a much safer thing. Not everyone who speaks Spanish uses it the same way. Some words are innocuous in some regions, but offensive in others.
