> But the guy takes his craft seriously, he demonstrably builds high-quality software that many, many people happily pay money for, and generally knows his stuff.

He has made a few good games, but how has he done anything that would paint him as a competent language designer? Frankly, Blow has done very little (up to and including being a non-asshole) that would make me terribly interested in what he's up to.

Paul Graham is on record that the best languages are built by people who intend to use them, not for others to use. FWIW, I agree.

The jury is out on Jai, but it’s clearly not a toy. John emphasizes important stuff: build times, SOA/AOS as a first-class primitive, cache-friendliness in both the L1i and L1d. And he makes pragmatic engineering trade offs informed by modern hardware: you can afford to over-parse a bit if your grammar isn’t insane, this helps a lot in practice on multi-core. The list goes on.

And “he made a few good games” is really dismissive. He doesn’t launch a new game every year, but his admittedly short list of projects is 100% wild commercially and critically successful. On budgets that a FAANG spends changing the color of some UI elements.

And that’s kind of the point right? Doing better work takes time, and there is in fact a lucrative market for high-quality stuff.

As for him being an asshole? He’s aspy and curt and convinced he’s right, which is a bad look on the rare occasions when he’s wrong.

But Bryan Armstrong is on the front page doubling-down on such bad treatment of his employees and shareholders that they are in public, written revolt. This may have changed since I looked, but no one is calling him an asshole.

A world in which a passionate craftsman misses on diplomacy while discussing serious technical subject matter is an asshole but a well-connected CEO revoking employment offers after people already quit their old job is “making the hard calls” is basically the opposite of everything the word “hacker” stands for.

Asshole.

How is that dismissive? He has indeed made a few good games, but making good games doesn't certify you as a language designer any more than it makes you a good plumber or equinologist. Hollow Knight is my favorite game of all time, immensely successful both critically and commercially, and yet if Team Cherry were to release a programming language I reserve the right not to be terribly excited about it.

> But Bryan Armstrong is on the front page

OK, Bryan Armstrong is an asshole. I can call two people an asshole. I can call more people than that assholes too, if it comes to that.

> Asshole

Because I'm dismissive of Jonathan Blow? Listen, if you want to fanboy/girl your brains out over the guy, be my guest. He just doesn't impress me all that much and I don't think "aspy and curt and convinced he's right" is anything remotely approaching an excuse for poor behavior. I've been told I'm on the autism spectrum, too, yet I manage not to act like an asshole. Though clearly you disagree.

The cherry-pick quotes from parent and refute is the laziest form of argument on HN.

In this instance, it allows you to blow past the few concrete examples amongst many that I cited where Jai is trying new things in the language space. It’s not hard work to learn a little about Jai. Jai may be an utter failure, but it’s not a toy or hobby, it’s being co-designed with an interesting game engine that looks pretty hot. It’s at least as expressive as C99, compiles way faster on modern gear, targets LLVM and x86, it’s at a minimum interesting.

Calling someone who does their homework a “fanboi” is A-ok, but someone else is looking for an excuse for poor behavior?

You can watch his Twitch streams and see what he does and how he uses the language.

He's developing at least two games using it (the development of one of them he also shows on stream) and so far it's been proven to be a very strong contender for a C-like language suitable for game development. Just the fact that his entire 3-D game builds in under a few seconds is definitely something to aspire to.

Not necessarily. Speed is actually very easy to come by if we push down quality to the level of "wrong answers infinitely fast", which trivially allows you to achieve as much computational performance as a broken clock. As well, if you write code solo or in a small team, you will almost always get a more consistent, higher quality result than if it's written at corporate scale because that eliminates incidental communication overheads that get reflected in the software dependencies(e.g. Windows Terminal's low performance is mostly an artifact of Microsoft's processes).

Jon and the authors of uxn commit a common fallacy in that they're chasing a brass ring of in-the-small performance metrics, getting it in the form of particular demonstrations, and then gradually accreting features to it until, most likely, they end up in a similar position to the old tech. Many software projects start off as the "light and simple alternative" and then develop into something not light and simple. This isn't necessarily an issue for any particular project, because if you know the goal of your tech, you don't need all the features and so can omit some things to claim a definite advantage for the application; but it's not in and of itself a solution to the general issue of making computing better, because it entails bespoken effort from expert practitioners, while the general trend in computing tech is the same as most industrial automation - it's quality-first. Quality comes first when you automate, because a superhuman level of quality can redefine what's possible, and it can compensate for the downsides of not being a bespoke, artisanal result.

The actual problem faced by language authors is that they face difficulty in defining quality while also generalizing the problem space. New languages are mostly "old concepts, new syntax and libraries" - still giving improvements in UX and therefore quality, but with most of the features carried over from previous languages.

The authors of this post note the same tendency with Gemini [1] and demonstrate that the clients are actually quite fat, much fatter than their rationale documents claim they should be.

If creating full games is an in-the-small performance for a particular demonstration, I can't even imagine what an in-the-big is.

As far as I can tell, jai is exactly that. It's already dropped a few features that looked fine in theory but didn't work for actual development.

I can watch coworkers blaze through Common Lisp in emacs, that doesn't mean it's the Next Big Thing in developer experience and performance.

The privacy of development has made Jai less than compelling, for a lot of us I think. I'd be personally more excited if I could use it and poke around at it, rather than see someone tinker on video streams. I get why he's doing things that way, but it's just hard to feel like it's going to be meaningful for anyone but him so long as it's kept hidden away.

[benreesman]

I appreciate that the Jai closed beta is atypical for compilers these days, and plucks some strings about the bad old days of proprietary build chains.

With that said, it’s on record that an open source release is planned, and whether or not it works, it’s not insane to run something past 100 early adopters before putting it on GitHub.
