Is Bitcoin about to be broken by quantum attacks soon?

Today's report from Google has caused quite a stir, but I personally feel it has been overly interpreted emotionally.

Google is not saying "Tomorrow quantum machines will be able to penetrate all cryptocurrencies," but rather saying: according to their latest resource estimates, the day when existing public key cryptography systems could be threatened might be closer than many people previously thought, so the entire industry should migrate to quantum-resistant cryptography now.

I think this is indeed a question worth deep consideration, and it is a core issue that the Bitcoin community should focus on the most.

Currently, Bitcoin's slow upgrade is both an advantage and a disadvantage, but technically, the introduction of quantum signatures through soft forks (such as lattice-based Dilithium, hash-based XMSS, and other NIST standards) is completely feasible.

The community is already discussing similar BIPs, so there is actually time to complete these preventive measures.

Google’s report also states that the remaining time is still greater than the time required for migration; it’s just that the window is getting narrower.

Additionally, companies like Project Eleven obviously want everyone to panic now, because what they are selling is post-quantum wallet/protocol solutions.
