TikTokers ("influencers" in general) don't do their editing or any part of their "production pipeline" on computers, kids are doing the full thing via smartphones nowadays. Blew my mind initially too, as I always did "serious work" at a computer and never the phone, but seems they're managing it somehow.

They use CapCut which is free and on the web and Google Docs.

To them what Apple just announced is trash.
