TikTok is definitely a threat to society. What mainly leads me to think this:
Users who are unable to logout and put their phone away, even for a few seconds, no matter whatever else they are doing.
Users who seem to believe that the incessant noise from their phones is fine for everyone else, no matter what time or place. The scary thing is that they don't even realize how ignorant they are being.
Users who will look at anything, no matter how unfunny or uninteresting it actually is, just to be looking at something constantly.
Minds are currently being conditioned into displaying these behaviours that demonstrate it's the most important thing in their lives, even though they don't realize it. Once there is a sufficient mass of the population displaying this behaviour, then they (we) are primed ready for a takeover.
Just a view, but the behaviours are there for all to see.
