Right. Satoshi Nakamoto created Bitcoin. He's a genius. Bitcoin systems and communities are working perfectly, and everyone is crazy about Bitcoin. But what happens if someone creates a blockchain that is faster and better than Bitcoin and puts it out into the world without any greed, as Satoshi did? Are people going to ditch Bitcoin away? In that moment, we're going to see a blockchain that's performing better than Bitcoin and is perfect for decentralization that everyone emphasizes. What will happen?
There are already lots of blockchain networks that are faster and cheaper than bitcoin. Look at all of its hard-forked coins. Every time dev saw a problem with the bitcoin network and they couldn't change the core network they tried to create a fork that could work better than bitcoin. Are they more popular than bitcoin right now? There are some obvious reasons why bitcoin is still dominating.
What satoshi nakamoto created was unique and any upgraded version of his idea will not get the recognition that bitcoin has. Bitcoin was created to give people financial freedom. If someone comes up with a better idea that can reach this goal in a better way then there is no point in using that instead of bitcoin but it needs to be unique, not an idea copied or inspired by bitcoin. With a new technology and concept we can have a bitcoin competitor, but do we really have that technological advancement now? I don't think so.
