Quantum resistant addresses are the ultimate solution to the threat that quantum computers will pose on bitcoin. To cure something is better than to treat something. If something is curable, people will go for the cure instead. Bitcoin can become quantum resistant but with the recent approach if accepted, the transaction fee will be higher than before.
Quantum computing is still in development, it’s not a real threat for now, even if it becomes one in the future.
The rate of quantum computing advancement can be since like the advancement in AI. I hope you can understand easily with that comparison.
