To you it seems simple, but this is a philosophical question that hasn’t been answered for over a century. You can reason for any point in time to be the point it becomes a person.
You have definitely less people here than on reddit. And the kind of people that even consider leaving reddit because of the reason we left and then chosen lemmy are usually mostly tech nerds. Other people don’t care and stay at reddit or twitter or go to the Facebook clone threads.
Your goal here should be information, fun and entertainment.
I personally also read reddit aside to lemmy, but I first go to lemmy and then to reddit. Yes reddit is bigger and has a more active community but it is mostly toxic and ads infested. Without revanced I couldn’t stand it.
