Quantum Computers Are Not A Threat To 128-bit Symmetric Keys (words.filippo.io)

AES-128 is safe against quantum computers. SHA-256 is safe against quantum computers. No symmetric key sizes have to change as part of the post-quantum transition. This is a near-consensus opinion amongst experts and standardization bodies and it needs to propagate to the rest of the IT community. The rest of this article backs up this claim both technically and with references to relevant authorities.

As expected the same dipshits pushing AI also lied about what quantum computing even is.

I'm imagining if I had said this even a month ago even though it's what I've thought for years.

It's most likely not the same people, as AI destroyed quantum computing. A person strongly invested into quantum computing would be crazy to push for AI.
