I want to create AI communities from reddit and ask the community members to switch to lemmy.

The communites from reddit that I want to create on reddit are r/singularity, r/OpenAI, r/ChatGPT, r/Grok etc.

Which instance would be suitable for it? Is lemm.ee big enough to handle an influx of users? Or should I use lemmy.world since they’re going to be global users interested in AI?
