The risk of advancements in technology to crack cryptography is probably another one. I don't know how severe that problem is and people say the algorithm could quickly be adapted, but if somebody cracks the algorithm I doubt that will ever become public knowledge until the harm done is really extraordinarily big.
If that does happen, crypto is probably the last that will get affected. The algorithm is used by others such as banking etc, and cracking crypto might not be as profitable as social engineering, doing ransomware, etc. Which is why most attack happens through spam e-mail, phishing link, etc.
