From my point of view, it's not quite like that. As I see it, it could be a threat in 15-20 years or more, but it's not imminent or impossible to patch ahead of time. It could be, but only if cryptography has stagnated during that period. Otherwise, this is the equivalent of the Y2K scandal, where just a date change generated hundreds of catastrophic news stories.
Threat or not, the warning is already in the air with so much news about it. Therefore, this diminishes the threat because cryptographers have had their eye on alternatives for a long time, and possible options in Bitcoin to combat this are being debated.
I see it more as another step in the evolution of cryptography, since a paradigm shift is expected. However, what we're experiencing now with quantum computing in relation to cryptocurrencies is similar to what happened decades ago: DES, RC4, MD5, Sha1... all discontinued, and we successfully migrated to other systems. In other words, it's good to take precautions for the future, but not to sensationalize everything.
The threat exists, but I believe it's not for the cryptocurrency landscape as such, but rather for governments and sensitive materials, since everything protected with current encryption could be stored and brought to light years later upon decryption: "harvest now, decrypt later."
I have seen many similar topic disscusiion on maany places where people were having discussions on the same points. But no one was so sure about the future, whether it will damage the bitcoin and other countries' currencies or will help them to keep the crypto space enviroment more stronger. So, there is nothing wrong in saying this; all we can do is speculate about this technology right now, and no one has any idea how the technology will be used.
For just now, I am putting an example in front of you of recent days' AI systems like ChatGPT and many more, like video-making AI tools and images as well. Such tools are being used for both purposes by different people; I mean, it is also being used for evil tasks or also for good tasks at the same time. So, its all depends on the perosn that is using it. And same here, the usage of Quantum computing will also depend on more who is using it for what performing kind of task. Well, this is my point of view. What do you say?
