If you don’t like this article: I was very careful when writing this piece to avoid qualifying or couching anything I say. This article is catharsis borne of my the daily frustration I feel when I know there’s a better way, but I’m not empowered by my job to take it. There’s even a handy list of at the bottom of all the things I removed.
Stop Whining About Rust Hype
Every discussion involving Rust ends up with an interminable thread complaining Rust “hype”. It’s “overhyped”. How much you hate hearing about Rust everywhere. Rust, Rust, Rust! Won’t all these “fanbois” just go away and stop talking about Rust?
Do you remember when Java was the hot new thing? No, probably not. You’re probably too young. Well, back in the day, there were trade magazines written on actual dead paper, but about computers (weird, I know). Those magazines were full of articles about Java, its promise, and the problems it would solve. The Internet (back when it was capitalized) wasn’t yet a hate-powered echo chamber, so instant knee-jerk reaction boiler rooms weren’t as much of a thing but the complaints were the same. Too many articles about this unproven technology. Nobody used it, so nobody knew it. Nobody knew it, so it couldn’t be adopted. Virtual machine runtimes had been tried before, C and COBOL were good enough, I’m tired of hearing about it, and on and on.
We all know how that ended. Java lived up to the hype, and ate the industry for 20 years. Let’s talk about why you need to stop whining about the hype.
Why Is There So Much Hype?
These problems, entire categories of problem sets, exist as “background radiation”. Everyone complains about them all the time, but there’s no solution to all of them. With Rust, you’re hearing about a technology that can solve all of them. Now instead of a many-to-many problem-to-solution mapping, it’s many-to-one. Now people talk about solving your problem, and your problem category, and other entire categories of problems to boot! This makes it feel like Rust is everywhere, all at once, because it’s relevant to everything we do.
Stop Lying to Yourself
It’s a hallmark of techie-types, of “engineers”, that you’re adept at assessing systems dispassionately. You can put aside the “hype” and consider solutions on their merits. You can decide based on fact, and not emotion. Resistance even to discussion of Rust because of “hype” belies the truth of that. It’s ad hominem in the extreme.
Whining about Rust hype is damaging and insulting because, in doing so, you’re accusing me of acting in bad faith. I’m not a shill. I don’t get paid by the Rust Foundation to convince you to buy Rust Enterprise. I’m also not an idiot. I’ve been programming for 30 years. I’ve successfully done big refactors in languages that don’t have type safety. I’ve written fast services in languages that incur GC overhead. I’ve written tight code in languages that don’t enforce good memory hygiene. I’ve done it on tiny micros, and I’ve done it on distributed multi-core clusters. I’ve been there. I’ve fucking done that. And I know a good thing when I see it.
I’m bringing Rust up in your thread because it’s relevant, and probably solves a problem you’ve got (even if you’re inured to it). I don’t owe you an exhaustive pros-vs-cons article any time I write anything. If you choose to disagree with me, disagree with me on the merits of what I’ve said, and please respond to me in good faith, as I say what I say in good faith.
Stop Tone Policing
But most of all, stop tone policing. That’s exactly what you’re doing when you complain about “too many” people “overhyping” Rust. Complaining about that is complaining that people are saying anything at all, or saying it in the wrong way. If you’re tired of hearing about it, well, I’m tired of hearing about half-solutions and solved problems causing trouble yet another time.
I’m writing because I have something to say, and that’s the point. You’re welcome not to read it; I won’t be insulted. You don’t owe me your attention. But I also don’t owe it to you to cater to your delicate sensitivities and apologize for every other excited person who also writes about Rust. Most of all, I’m not going to stop advocating for something I believe will materially improve the industry (and my job satisfaction).
Java was also a “fad” that would go away once the “hype” died down. And anyway, “real” programmers didn’t write Java, which I guess isn’t a problem Rust has because Rust is “hard”. (It’s not, by the way. It’s not hard. It’s truly not.) Nobody was threatened by Java because the growth of the Internet (and the industry) meant nobody was competing for your job, only new jobs. And because snobbish attitudes kept a cynical separation between the “real” programmers and the unwashed masses.
An ability to compensate for the shitty state of technology that exists today isn’t some kind of a competitive “moat”. Nobody thinks you’re smarter or better because you can remember all the pitfalls. Learning all the tricks and caveats to avoid problems is the equivalent of learning alchemical potion recipes. Someone who could learn these things but doesn’t have to spend the energy on it is going to eat your lunch. Some company that saves money by not spending as much on debugging or refactoring, and that avoids paying for security fire drills, and saves money on hardware costs by running close to the metal is going to eat your lunch. I can write Rust as quickly as I can write Python, and other people can too. Time-to-market matters, and the gap between Rust and scripting languages is closing fast. Soon your solution won’t be faster to market, and will be more expensive to maintain to boot. And someone’s going to eat your lunch while you complain.
There is a competitive advantage to knowing Rust right now. Hiring managers are using it like a filter for the best people because knowing Rust helps you write better code in other languages. In the near future, it’s going to be table stakes, and shooting all the messengers in the world won’t change that.
But What About…
A list of polite things you expect me to say, but I left out:
- Java failed in as many ways as it succeeded.
- There’s a time and place, and you don’t want to drive people away.
- Some people have known about categories of problems since the 60s and have tried solving them before, and failed.
- Maybe all the code I’ve written over my career sucks.
- Sufficiently skilled programmers can overcome or avoid the pitfalls of other languages.
- You can write bad code in any language.
- You can write insecure code in any language.
- I’m not talking about you, specifically, dear reader. The general you.
- Rust doesn’t solve every problem, of course, so I won’t claim that it does.
- I have seen other good tech that isn’t Rust.
- Rust is a big language so there’s a lot to learn, and that’s hard.
- It’s hard to measure how much Rust improves things.
- Some of Rust’s difficulties and problems can’t be solved and never will.
- Working with shitty technology is a competitive advantage, it’s just not a growth market.
- Maybe working with shitty technology is a growth market, because we keep making more.
- Maybe Rust is more shitty technology, and I just don’t know it yet.
- The speed at which I write code is not actually impressive.
- Please, I’d prefer it, it would be better if, won’t you, I’d like it, I’d appreciate it, but I can’t tell you what to do.
- This article is whining too.
