Though we don't want to lose the Bitcoin creator, everyone has to leave one day. But his disappearances aren't actually related to Bitcoin. Because Bitcoin has been designed in such a way that anyone can run the blockchain, It's not centralised with any authority, like digital fiat. So any particular operator isn't required to run the Bitcoin network. It's because of decentralisation, not only for open sources. Because open source helps you read codes, copy, clone, and run your own way. But anything can't be modified on an existing blockchain. So even though there is no Bitcoin guardian, we shouldn't worry anyway.
Actually, we didn't lose the creator of Bitcoin, Satoshi just disguised his identity for the safety of himself and his family.
I'm sure he monitors every development that happens to Bitcoin and just looks at how Bitcoin can develop so far, even though it doesn't have any guards and the system runs by itself and is already arranged in such a way.
And a few days ago there was an X account (twitter) that claimed that he was Satoshi and was actively making a tweet.
Bitcoin is a predicate machine.
"Over the following months, we shall explore different aspects that were not explicitly contained within the white paper.
These aspects are all parts of bitcoin, and are important.
Some of these ideas were touched upon in the early years; now is the time to extrapolate and explain"
