As far as I am aware, the NSA seems to have classical computers that can break 2048-bit RSA today.

The idea of using QC for codebreaking was kind of cool in 1990, but Moore has had 35 years to catch up with the hype.

I don’t believe specs were ever released, and the only inference was that 1024-bit was possible.
It seems strange that today’s key strength guidance would be within what’s publicly known to be crackable with today’s technology.

I wish humanity would not be so obsessed with superiority. It's disgusting.
In the same way technological advancements in radar and signals brought aerial superiority, the first-mover in PQC will bring both technical and cybersecurity superiority.
In 2015 people assumed we'd need 1 billion qubit computers to break 2048-bit RSA.
That estimate changed to 20 million in 2019.
We're 5 years on from that and quantum supercomputers are 16x more powerful than they were in 2019.
Based on our current rate of advancement, we'll likely be there within 10 years or less, even if the estimated amount of resources required don't decrease from improvements on the cracking side.
