Well no one really knows, no one can tell what is going to happen to Blockchain tehcnology in the next 50 years, it could be a success or there could be a new technology that has replaced it. Well let's just all hope for the best.
The blockchain is probably going to be around for a long time, what we do not know is if it's going to be around for a long time is bitcoin, there are many coins trying to take its place and there are many governments trying to destroy it or to replace it with their own currencies, that is what we really do not know the future of bitcoin.
i think so, blockchain will live for a long time, because this is a technological development with many advantages, such as speeding up delivery time and also transparency. and indeed the government will take its role here
