Better than every user from Reddit coming to Lemmy, for a few reasons:

• servers would crash
• the reddit "hivemind" would move to Lemmy
• the shitty jokes would continue here
• just check r/redditmoment, do you want that to become c/lemmymoment?
• right now the community here is big enough that there are enough posts to keep us entertained, but small enough to get to interact multiple times with the same people and not get drowned in a sea of posts/comments
• the Lemmy community rn is also formed of at least mildly tech-savvy people (that could figure out the whole instances thing), that isn't the case for Reddit
