Not comparable. Wikipedia has always had a strict policy on citing sources. ChatGPT can't cite sources by design, because its answers are based on synthesis.
It wouldn't be too hard to program at least gpt3 to basically take a chatGPT answer, go to google, scrape results and verify if the chatGPT answer was factual or not and maybe give it a score or rating of factual-ness.
Simple answer adhd, if I could ship a product I'd already probably be rich, instead I'm scraping by as a freelance dev. Though, chatGPT probably could help me code it anyways lol.
