I surprised when I read the title but quickly when I visit X, I realized it is very possibly not a real account of Satoshi Nakamoto. Because the account was registered in May 2018, not more years farther in the past like 2010 or 2011.

satoshi account on Bitcointalk was last active on December 13, 2010. So a Twitter account registered 8 years later does not make sense and can not convince me that it is actually from Satoshi Nakamoto.

That account is possibly owned by someone else, not the founder of Bitcoin, so that tweet is not serious.
