So, as for whether Satoshi Nakamoto is still involved in the project, that's actually a bit of a mystery. Nobody knows the true identity of Satoshi, so it's difficult to say whether he or she is still working on Bitcoin Core.
Personally, there are some people who speculate that Satoshi might still be involved in the project anonymously. It's certainly an interesting thought
The identity of Satoshi Nakamoto, the creator of Bitcoin, has always been a mystery. No one really knows who this person or group of people really was, and this has led to a lot of speculation about their involvement in the project. As to whether or not Satoshi is still involved in Bitcoin Core, it's hard to say for sure. Some believe that Satoshi may still be working on the project anonymously, while others think that they have moved on to something else entirely.
While we may never know for sure whether Satoshi is still involved in Bitcoin, the idea that they might work on the project anonymously is certainly appealing. After all, the creation of Bitcoin is a tremendous achievement, and it's hard to imagine that its creators would just walk away from it. Whether Satoshi is still involved or not, their legacy lives on in the form of Bitcoin and the many other cryptocurrencies that have emerged since.
