What is your opinion on the view that Laogao and Xiaomo's video content sometimes lacks rigor?

This really depends on how you view the positioning of their videos. Lao Gao and Xiao Mo's videos primarily aim to be light and entertaining, covering topics like science, unsolved mysteries, or general trivia. They're more like "edutainment" than serious academic lectures. So, when you say they "lack rigor," from a purely scientific standpoint, they sometimes oversimplify too much, or individual statements might not be entirely accurate, or their sources might be unreliable.

However, if they were to produce videos strictly to academic standards, many people probably wouldn't watch them. Their style involves using exaggerated and humorous ways to make topics interesting, encouraging more people to click and learn. It's like watching a variety show – you don't take it too seriously, but if you learn something, it's a bonus.

So, I think as long as the audience is aware – knowing it's not a textbook but a "chat show with a bit of knowledge" – then it's perfectly fine. If you truly want to delve deeper into a topic, you can always seek out professional resources later. It's inherently difficult to achieve both entertainment and rigor, and they've chosen the path of keeping people entertained, which is their own unique positioning.
