That's great if it works. But it's way harder to produce a formal proof. So my expectation is that this will fail for most difficult problems, even when the non-formal proof is correct.

Even if they take the same number of ticks, shouldn't xor fundamentally needing less work also mean it can be performed while drawing less power/heating less, which is just as much an improvement in the long run?

That wasn’t much of a concern in the 70s and 80s.

Also, you probably spend much more energy moving the bits around the chip and out to RAM than you do on the actual calculation.

*user-mode code.

Your city/rural distinction is insightful. I think it can be taken into account relatively easily. Name explicitly the cities/locations were the requirement would apply. Possibly based on some objective criteria like population density.

Can such policies be implemented individually by cities?

Not sure about the legal frameworks in the US but that’s exactly how it works in most places in the UK. Cities have restrictions for on-street parking (metered, permitted, illegal) whereas the towns and villages don’t (unless they also bring in bylaws to help with congestion).

In the US it varies a lot based on what state you're in. Some states give the cities a wide latitude for such policies, but some states (notably 'red' ones where the state government is likely to be conservative and the cities are likely to be liberal) do not grant cities the flexibility to make ordinances like this.

Also restrictions such as residents only parking in both cities and towns.

> not doing the proper reviews, but once again, this is not remotely unique to AI code; this is what 99% of companies are already doing.

But is the scale similar, or will AI coding make the problem significantly worse?


If you're not doing code review, you're not doing code review. If you're not gating builds on code review, you're not doing code review. If your developers are lazy and just approve the PRs as they land, you're not doing code review.

If you're thinking there is some magical line where LOC < n gets properly reviewed, but LOC > n doesn't, I assure you that's not the case.

And no one is turning off their approval gates in their build pipeline just to accommodate AI code.


> obviously no one’s running any compiled Lean code in any kind of production hot path

Ignorant question: why not? Is there an unacceptable performance penalty? And what's the recommended way in that case to make use of proven Lean code in production that keeps the same guarantees?


Yes, it isn’t performant. Lean isn’t a language for writing software, though you technically can; it’s a language for proving math.

Where are you coming up with this from? This is awfully confident for a fact you seem to have conjured up without evidence. As far as I am aware, Lean is interested in being used as a programming language (see: https://lean-lang.org/functional_programming_in_lean/) and people are deploying Lean in production: https://docs.aws.amazon.com/clean-rooms/latest/userguide/dif...

You’re right, there is that one example. Feels like we’re in exception that proves the rule territory. But I’d be very interested in being proven wrong! This isn’t a desire of mine, just what I’ve seen. Do you have other examples?

Also, part of my confidence comes from both having been a professional programmer for decades, across many languages, and also having programmed in Lean. It’s a great language for math, perhaps the best choice right now. But as a general purpose language it’s incredibly quirky.


> A country where no one is stigmatized for loving someone differently than the majority.

-- Peter Magyar victory speech, April 12, 2026

That's directly in opposition to Orban's views and homophobic laws.


Shit, i didn't realize, his name is really Magyar? I thought it was a surname. What a name for Hungary's president


On a similar note, François Hollande had the right first name but the wrong last name!


"Russians go home" was one of the main chants at opposition rallies. In 2026 like in 1989.


And in 1956 of course.

> Someone in power doesn’t get to choose - the board of directors do

Since the board of directors can decide to replace the CEO, it's not the CEO who holds the (ultimate) power, it's the board of directors.


Since the majority shareholder(s) can decide to replace the board of directors, it’s not the board of directors who holds the (ultimate) power, it’s the majority shareholder(s).


Indeed, and there we reached the end of the chain.


Sure, but if you constrain to fixed output length, you will definitely have collisions (Pigeon Hole Principle). There's no way around that.


padding with zeroes to a fixed length and prepending the original length would suffice, but you’d have to have a fixed length of double infinity to account for both the length information and the hash information, and the hash is less efficient than the original information.
