The only time I ever had Tik Tok was for a school assignment, and we HAD to make an account. I was dreading the idea of ever downloading it. I just quickly found a video for the assignment and promptly deleted the app. I've definitely thought about getting it (for more than an assignment lol), but I'm sure I'd fall into the rabbit hole, and I'd rather not do that. I've already got Youtube, Instagram, and Pinterest to keep me entertained on social media. If I really want to watch Tik Toks, I'll wait for Youtube to recommend me a Tik Tok compilation video (which are pretty much just of cosplays, art, and LGBTQ stuff). The only reason I'd ever get one is to post cosplay Tik Toks, and even then, I don't think I'll ever cosplay enough to make frequent videos. Part of me still thinks of the 2018 cringe days and refuses to download because I will forever associate it with that cringe, even if it's gotten better since then.
TLDR: cool in theory but no
