Today, Google claims it will soon be possible to break in-transit (mempool) TXs in 9 minutes.
This seems quite a suspicious number because the block time is 10 minutes, it seems to me that someone manipulated the outcome of this paper in order to tailor to a result. When extremely complex stuff ends up coincidentally on favorable numbers like this, it indicates that something is fishy even if the whole thing may be valid. I would have believed it even if they said something extremely low such as 1 minute, but this number is fraudulent. Perhaps a researcher biased or bribed in order to tip the data a little bit. Happens almost daily, even in medicine but most people here wouldn't know that.

This is nothing compared to the in-transit claim, and for previously exposed keys we do not have a solution. They may stay as they are or get merely slowed down with the hourglass proposal or something similar.
Maybe pretending that we're not there yet doesn't end well if we simply count down from 1 million to zero, in bigger and bigger decrements.
You seem to misunderstand this space entirely. Let's all pretend that we are already there. What now? Nothing. We do not know what the right solution is, there is no assured solution yet. There are many bad solutions to this, so stop believing that people don't want to do something about this because that is not accurate -- the problem lies in what exactly should be done and how. Many things are still in their maturation process.
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.
Other than educating people to not resuse addresses, "community members" should not do shit about this. When "community members" start getting intensely involved in topics that go way beyond their head, we get another misinformation shitstorm like we did with OP_RETURN. Let cryptographers do their jobs, developers will implement solutions when they are available. If randoms start getting emotionally invested in
individual quantum-proof signatures or other solution methods, it will just lead to useless bickering over false claims.
Assuming that there is a good candidate, deploying a new address type with quantum safe signatures is easy. The issue with old coins, reused addresses and that will remain open. Still people forget how this world works. It is not going to be some random hacker in the world that will be able to steal money using this as he can from various shitcoins and their Defi protocols. Google is not legally able to steal any of these coins so even once they succeed it will remain merely a demonstration of what can be done by an extremely well funded and state of the art actor (not by everyone, not by random small or medium entities). What do you actually think a public company is able to steal digital property from others legally, including other legal entities from the USA?

I actually got a bit paranoid last year (reading about QC) and moved all the remaining coins in Legacy Addresses that I HODL from back in the day.
Unless you are referring to P2PK addresses (and taproot but this is less of an issue for the network as a whole as of today), this did not do anything. Only unused P2PK addresses are vulnerable. When it comes to resused addresses, all types are vulnerable. Most people have never seen a P2PK address in their wallet.
There is this terrible negative side effects from technology and social media that pushes normies and average people into getting involved in every topic that exists. Sit the fuck down,
know your place and don't do anything. The illusion of knowledge is the greatest danger that exists in this context.
