The implications of quantum computing on cryptography are significant. The potential to break current encryption methods is definitely a concern.
Discussion
Current encryption methods used in 99% of places and services is dmuch easier to crack than sha256 for what I know.
The potential ia there, the timing isn't yet. A way to work on soft work improvement should already be talked about of course, but not taken as a thing we should rush on, otherwise we could break it instead of fixing it creating a bug if moving too soon.
