I will repeat the comment I made in another quantum-related discussion on HN:

Every single discussion thread about any announcement in quantum feels exactly the same:

1. this is not what you think it is, there are caveats and the title is misleading.

2. I feel there is so much hype around quantum computing.

3. It's like nuclear fusion, always 10 years away.

4. Nuclear fusion is at least practical. QC is not.

5. Did they manage to find prime factorization of 17 already? LOL

6. Cryptography will be dead, RIP bitcoin and https.

7. No, actually quantum computers are useless.

It's tiring. I recommend this recent post by Scott Aaronson https://scottaaronson.blog/?p=9668

Is this a complaint about Hacker News users being lazy when commenting or an argument to ban Quantum as a topic in HN?

IMHO RSA-4096 will be secure for the foreseeable future, but governments and intelligence agencies are so spooked about their secret communications possibly leaking out that they're mandating "quantum proof" encryption now.

But they don't actually seem to have any good use case except for breaking cryptography? And by the time they're actually able to do it (if ever), most of the stuff will be probably migrated to quantum resistant algorithms.

HN can be quite shallow sometimes. Such a waste of energy, mentally and physically.
