More than quantum threats and even more than spam, I am concerned about the lack of interest in Bitcoin privacy.
However, as you know, without privacy there is no freedom and so on.
That said, it's also worth studying what Signal or SimpleX have done with regard to quantum computing. It's all about assessing the risk-benefit ratio, which is obviously not the same in Bitcoin as it is in Signal.
Just another drama, while the bad guys continue to win day after day, as the world gets worse and worse and Bitcoin has failed to solve anything (and neither has Monero 😂).
