I have made peace with the fact that more thread on quantum attack on Bitcoin and how is going to happen tomorrow.

Quantum vs ZKP?  I don't think you understand what ZKPs are.
ZKPs excel at proving statements without revealing data. It helps in enhancing privacy, scalability, and functionality on Bitcoin like PoR(proof of reserve) for exchange audits

The best it can do is play a support role in improving privacy while acknowledging One owns a UTXO without revealing the Pubkeys.
