I saw an interview with Elon Musk, where the host asked him what he thinks is the worst thing in the past 10 years. He thought for a long time and said: "Short videos."

Yes, I deeply resonate with this. Short videos have a very obvious impact on people. Fewer and fewer people have the patience to finish reading a valuable article, fewer and fewer people have the ability for deep thinking, and fewer and fewer people possess writing skills.
Deep thinking will become an even more scarce ability in the future.
