Quantum computing risk cannot be ignored. "Without cryptography, we essentially need to “unplug” from the ICT infrastructure, and stop using untrusted parties and media. This is simply not practical for the majority of applications, including anything involving a financial transaction that uses real-time communication (credit card purchases, money transfers, online banking, etc.), online communication (e-mail, texting, social media, etc), online advertising, e-health, and so on."
