What will replace TikTok?

When I was in high school, VINE was huge. Some major stars began on VINE. When we lost VINE, these influencers moved to YOUTUBE and then came TIKTOK. At least that is my memory. We have facebook REELS, instagram, and youtube shorts… but TIKTOK is known for its bottomless scrolling through short videos instantly upon opening the app. What is going to replace TIKTOK? I think VINE replaced TIKTOK in terms of culture and format. I do not believe instagram, facebook, or even youtube can do it. What’s next? Many social medias have a great downfall. People are going to want something that is a replacement for TIKTOK, but I don’t see them wanting instagram to do it. I don’t see FB doing it. Youtube would have to change the format of their app. Youtube could make a youtube shorts app, or do they have that? What is going to be that app that people end up HAVING to download because their friends are sharing videos, and the app format is just better? Opinions?
