I don't even want y'all to dunk on this, I just want to share this because it's so funny. no dunking if you can resist 
If you don't know what this website is btw, if HackerNews is Reddit for tech bros, then TeamBlind is 4chan for tech bros. Unfortunately very useful for career related information and specific company/tech industry information since everybody there is obsessed with climbing the job ladder
The way information is presented is more important than the information itself. When you read a book, you can slowly consider the idea, you are actively and consciously taking it in. Tik Toks are the most passive form of consumption, with what you will see predominantly controlled by an algorithm you don't get to see. Things are suddenly and often bombastically thrust into your face, and explanations are condensed into mere seconds. People don't often question tik toks information as they should.
Anyway, your experience is not relevant to people that have a hard time reading, I don[t see why you piped up. Social media is definitely more addictive because people interact with it in the way of gamblers and alcoholics on a massive scale.
People tend to treat books as an authoritative source. Few people would treat TikTok as an authoritative source. In this way books can be more manipulative a form of misinformation.
I would argue it could be a means of democratizing information for people who don't have strong reading ability or don't have a long enough attention span.
I have seen people become obsessed with researching things much like people becoming obsessed with social media. I have even had this happen to me. Any novel source of information or stimuli can become addictive. To compare this to something physically addictive like alcohol is ludicrous though. You can't get withdrawal symptoms like seizures from not watching TikTok.
