Monero needs to step up for quantum safety, not by replacing the existing encryption, but by adding a quantum safety encryption layer on top. Google's recent paper on quantum risks to cryptocurrencies had identified Monero as being at risk. This is not tomorrow's problem; it requires initiating action today, so these efforts can bear fruit by the time the quantum hardware is ready, perhaps by 2029.
All coins are aware of quantum safety requirements, yet quantum computers are still far enough in the future that it makes sense to wait, and first see what those post-quantum mitigations should look like.
