Why now
TikTok, Reels, and Shorts are how most niches get discovered. The loop that still kills cadence is script, record, edit, caption, post. Most people break before the channel has enough posts to learn anything.
The pipeline can now run in minutes without a camera: script to captioned 9:16. Operators who lock a niche and a look while that is still rare keep the window. Everyone else waits until the feed is full of the same stock soup.
