Curate, connect, and discover
When I was younger, English was technically my second language, and my ability to interpret it wasn't very good.
I vaguely understood movies, but processing their plots were difficult, and my ability to read was superior to playing by ear. Turning on captions helped me understand and follow along much better.
It also quickly helped my vocabulary grow, so my writing vastly improved through it all.
I still put captions on today because sometimes I worry I'll miss context or confuse homophones.
Why do people need subtitles to watch a show in English? I don't get it. What is wrong with the ears of young people?
