What exactly has short video changed?

Short videos do not lower your learning difficulty, but rather make it impossible for your brain to enter the "deep processing mode necessary for enlightenment".

Step 1: Fragmented attention → Unable to maintain a sufficiently long chain of thought → Learning remains superficial

Step 2: The faster the pace of short videos → The brain becomes increasingly impatient with slow information → Automatically escapes when encountering long texts, technical issues, or abstract concepts

Step 3: The brain is accustomed to "a reward every few seconds" → The ability to delay gratification necessary for deep learning decreases → Reading, practicing, and reasoning all become "like hard labor"

Step 4: Unable to maintain long chains of thought → Unable to build models in the mind → No matter how much is learned, it cannot form a "sudden insight structure". Further down the line, the brain will form a closed loop: encountering difficulties in learning → feeling stuck → instinctively wanting quick stimuli to alleviate discomfort → opening short videos → dopamine spikes → further decrease in learning tolerance → becoming more easily stuck.

After a few cycles, your brain will learn one thing: as long as you need to enter deep thinking, it will magnify the pressure in advance, forcing you to escape. To put it more simply: short videos do not relieve pressure, but provide a "numbing" escape from pressure until attention and energy are fully squeezed out. In the long term, it can lead to "brain rot".
