Is crypto community ready for "post-quantum cryptography" era?

IMHO, I believe that quantum computing capability is a serious threat to Bitcoin and the existence of cryptocurrencies, and I'm already aware of it, But in that report that Chinese scientist has already achieved the quantum computing supremacy, I doubt it because it's too early to say that even in the Google's researched they admit that it's too complicated for now because of a missing" Ingredient" what I believe was its only a propaganda but not existed in reality.

I think that the real success in the creation of quantum computers will not be widely disseminated.  Moreover, in the first place they will fall into the hands of criminals.  Therefore, the fact that they were created and their good computing capabilities, most likely, we will find out when they massively hack our wallets with cryptocurrency.  It will be good if I'm wrong.  However, the incoming information about the success with their development makes you think a lot.

Mate, Dont just easily believe in a piece of paper! Just remember that we are living in the era of global superpower competition, with lots of propaganda have surfaced in most area, like defense, Space, and breakthrough, etc. How could we believe if they dont have shown it to the public for me the "quantum supremacy" is a complex idea that needs to understand more in order to bring it into reality. thats why I dont believe it for now! Bitcoin and other cryptocurrencies will stay in the race for sure.

I won't call this propaganda, they was an article that I read sometimes last year that Google also is making huge head way with quantum computing. Even without quantum computing attack some of these POW Altcoins are suffering 51% attack ETC recently. I think the only coin in the space people need to watch out for is Bitcoin, if Bitcoin is successfully attacked that is the end for all the space but I have a feeling we will cross the river when we get there

I would believe the existence of quantum computers when they are already at use and has already put a screeching halt to Bitcoin and cryptocurrency in general. I am sure that by the time this can happen we are already far advanced that an antidote for the challenge has already been set up. Anyway, it is exciting to see the race for the development of super computers and with China so eager to show to the world that they are already at the top and other countries not easily willing to give that recognition.

Previously, forums tried to prove that it will take many more years to create quantum computers. But I already read a long time ago that quantum computers of low power have already begun to be delivered to schools in China so that students have an idea of ​​quantum computing. If the very principle of quantum computing works, then the creation of a high-power quantum computer is a matter of little time.
It seems that humanity is not yet ready at all to eliminate their threat to cryptocurrency and other problems. When our wallets start to be hacked, without effective countermeasures, the cryptocurrency may lose its current value.
