The original dev lives in Canada. He made this fake account called "Armin Lebedev living in the Netherlands" and working for a company that doesn't exist (no result anywhere in all the search engines). He created this account to reply to other people, he has no other activity. All his replies are like:

Wes - Never take this post down. It's hilarious how people don't understand that this post was made on Dec 9, a whole 11 days prior to the tweet. Complete inability to read past a headline, and so confident about it too. This will go into the history books about how silly the anti-AI sentiment was.

I will just restate this fact about reality: Dec 20 comes 11 days after Dec 9.

That is indeed a screenshot. The tweet was made on Dec 20 (just like I told you). A date that happened 11 days after Dec 9.

Yes, that's him. But did you know that Dec 9 comes before Dec 20?

He's stalking a bit, spamming a lot, he wants to correct every reply to the post for no reason because it's not the same person of course (/s). This magical account that was created after the post is obviously fake and the same guy.
