Key words to that is "Estimate" and "Projected". No mention of the fact no one has yet to actually build a QC that has even a tenth of the number of qubits and gates required.
Edit: Fact is, no one has yet to build a physical, working, QC that can do anything more than act as very limited-scope testbeds to verify how the quantum circuits actually work and what areas need improvement. There's still a long way to go before anything resembling a fully functional QC is built that can even begin to address the problems that will be thrown at it.
OK, but what did Google currently discover that they shortened their "estimated" and "projected" Quantum Timeline? It's probably a suggestion that we as a community should also start having some awareness towards the Quantum Threat, no? Ignoring the situation, because "estimated and projected" won't make it go away.

The FUD is always way over blown. If/when a QC powerful enough is a reality, stealing Bitcoin is going to be way down the list of priorities for whoever possesses the QC power.
If it’s Google or some Government body they will not decide to start stealing Bitcoin. It’d likely be used to hack other countries classified info/documents. There would be a desire to get other countries nuke codes and stuff like that.
Bitcoin is not even a 2T marketcap, it’s a tiny market. A QC breakthrough would be huge, whoever has the power will not be rushing to do anything with Bitcoin.
I used to believe that Bitcoin should be the least of our worries if the Quantum Threat arrives, but Satoshi's wallet could be the first testbed for early Quantum Computers.
If you're a Core Developer, would you merely allow that threat not to be mitigated?
The point is awareness, which leads to a discussion, then a solution.
