On the one hand, it's comforting to believe that it's all rumors and nothing is going to change, but on the other hand, technology progresses extremely fast, so what might be currently true, might change in the near future. Look at the advance of AI, just within a year or two after it became mainstream, you can barely notice the difference between AI and real life in some cases.
My point is that the IT sector advances extremely quick, can we be sure that something similar won't happen with quantum computing? That's my main concern.
I do not deny that the development of technology is amazing because bitcoin is also the result of that development but everything has its own sequence and stage. We should not exaggerate the development of technology either. Like AI, many people are surprised or even scared when it proves superior. But if people take the time to learn, they will know that the development of AI has lasted for decades before it can be as perfect as it is today. AI has been researched and developed since the 1950s and 1960s, not just recently. Likewise, quantum computers have been around long before bitcoin was born, and for the past 16 years, quantum computers have remained just a rumor. Why should we worry about it?
Of course, it will continue to evolve but bitcoin core developers will also constantly work to help bitcoin adapt to any changes that threaten it.
