Exactly, this is the point. We never know the limits of a technology until it is too late. I am scared of this. My knowledge about Quantum Computing is very limited, I don't have the knowledge of the people who are debating here. But I think we need to be aware of QC since with AI things can get faster than expected. Of course, tech has also its limits and when it comes to quantum, it is such a complicated thing to develop. Also it is true that if Quantum evolves, we will be able to solve very specific and unbelievable problems and we will find solutions to certain issues. Maybe thanks to QC we will be able to protect #bitcoin and encryption better than we can do it today. We don't know which technologies will emerge from QC, maybe we cannot even imagine them today. For example, someone 50 years ago couldn't imagine the internet.
