QCs are completely unsuitable for reversing hashes and that is what cracking passwords needs.

Translation: we don't currently have a quantum algorithm for reversing hashes. But there was a time, not that long ago, when we didn't have a quantum algo for factorization either. However, I don't expect to see a quantum algo for hash reversion any time soon, because the whole problem of reversing hashes is pretty complex.

Factorization as a classical problem is essentially trivial, in that there are very simple classical algorithms for it. They just take a lot of time to run. But coming up with an efficient quantum algorithm was not trivial, and the algorithm itself isn't so simple. So you can estimate that a quantum version of any algorithm is a lot more complex than the classical counterpart.

"quantum resistant forever" is too strong.

I've only taken fairly general master's level courses in quantum information and regular cryptography, but I agree with this overall sentiment. My math professors used to say that no asymmetric encryption scheme has been proved unbreakable; we only know if they haven't been broken so far. Assuming something is unbreakable is like saying Fermat's last theorem is unprovable — until one day it's proved. So to me "post quantum cryptography" is essentially a buzzword.

That's not how it works. You can't just buy a tract of land. You have to buy the land, jump through hoops to get permits to build, defeat NIMBY lawsuits, get the local municipality to run services, defeat more NIMBY lawsuits, get new permits from a new municipality administration, then finally break ground on construction.

NIMBYs of all stripes throw up roadblocks during the permitting process and will then sue to get an injunction. If you defeat those lawsuits they'll go after the municipalities suing that permits were approved illegally (which they sometimes are).

After several rounds of legal wrangling you can finally start construction. This ends up with only huge developers being able to build because they can absorb all the pre-construction costs until they sell all the homes. They can also afford the scale to benefit from bulk orders and contracts.

The cost of expanding housing is mostly in the project development rather than labor costs of construction. Even if you had construction robots the construction companies would only offer marginal savings as their bids would just be human contractor - 1%. There would be no reason for them to leave money on the table offering a huge discount off human labor.

As opposed to depending on lithium produced in China.

What are you talking about? Do you have any idea what the carbon emissions of fossil fuel extraction and refining are? Do you think the sludge that comes out of the ground goes right into a gas tank?

Also, why are people comparing the ingredients of a battery — which is recharged a thousand times — against petrol, which you need to extract and process anew for every fscking "charge". I keep seeing this over and over, and I'm never sure if it's a new level of stupid, or just a very hairy troll under a very large bridge.

I'm a bit late to this discussion, but I also notice that the Hormuz Strait is being closed. Gas guzzler owners all over the world are whining over rising oil prices, while the civilized world is moving into energy sources that don't depend on access to conflict areas. The grandparent whines about China, but it's not exactly the sole source of Lithium. They even opened a mine here in Finland.

First off: Where in the hell did anybody get the idea that a web browser is for anything other than browsing the web???

Also, does anyone remember when web browsers were considered thin clients? I think the last time this was true was in the late 00s with netbooks. Then, more than a decade before the Al craze, browsers became these turbocharged Javascript engines that need multiple gigabytes of RAM to run.
