Elon Musk's X claims it's now a 'video-first platform'

Nope it's just his MO to phrase what he hopes to achieve some day eventually as if it's already/almost done.

Like he wants to deal with content moderation of video...

Most videos are radio shows... with accurate transcriptions.

he's already stated he wants a Chinese style app for everything.

I mean, he says it's going to be a different improbable thing every week or so, so probably not.
