I would like to gauge public perception regarding the plausibility of rise of quantum computer that is advanced enough to break all current cryptographic systems.

Out of these two options.

option1: QC in which can break pubkey before block gets mined. option2: Wireless shower that brings water to desired temperature and pressure without pipes and plumbing infrastructure (just a pure shower device).

Which option do you think is more feasible as technology continues to innovate?
