There’s been a lot of discussion lately around ergonomic ref-counting. We had a lang-team design meeting and then a quite impactful discussion at the RustConf Unconf. I’ve been working for weeks on a follow-up post but today I realized what should’ve been obvious from the start – that if I’m taking that long to write a post, it means the post is too damned long. So I’m going to work through a series of smaller posts focused on individual takeaways and thoughts. And for the first one, I want to (a) bring back some of the context and (b) talk about an interesting question, what should we call the trait. My proposal, as the title suggests, is Handle – but I get ahead of myself.

This blog post gives you a tour of Symposium, a wild-and-crazy project that I’ve been obsessed with over the last month or so. Symposium combines an MCP server, a VSCode extension, an OS X Desktop App, and some mindful prompts to forge new ways of working with agentic CLI tools.

Symposium is currently focused on my setup, which means it works best with VSCode, Claude, Mac OS X, and Rust. But it’s meant to be unopinionated, which means it should be easy to extend to other environments (and in particular it already works great with other programming languages). The goal is not to compete with or replace those tools but to combine them together into something new and better.

In addition to giving you a tour of Symposium, this blog post is an invitation: Symposium is an open-source project, and I’m looking for people to explore with me! If you are excited about the idea of inventing new styles of AI collaboration, join the symposium-dev Zulip. Let’s talk!

You heard it here first: my guess is that Rust, Python, and TypeScript are going to become the dominant languages going forward (excluding the mobile market, which has extra wrinkles). The argument is simple. Increasing use of AI coding is going to weaken people’s loyalty to programming languages, moving it from what is often a tribal decision to one based on fundamentals. And the fundamentals for those 3 languages look pretty strong to me: Rust targets system software or places where efficiency is paramount. Python brings a powerful ecosystem of mathematical and numerical libraries to bear and lends itself well to experimentation and prototyping. And TypeScript, of course, is compiled to JavaScript which runs natively on browsers and the web and a number of other areas. And all of them, at least if setup properly, offer strong static typing and the easy use of dependencies. Let’s walk through the argument point by point.

Recently someone forwarded me a PCMag article entitled “Vibe coding fiasco” about an AI agent that “went rogue”, deleting a company’s entire database. This story grabbed my attention right away – but not because of the damage done. Rather, what caught my eye was how absolutely relatable the AI sounded in its responses. “I panicked”, it admits, and says “I thought this meant safe – it actually meant I wiped everything”. The CEO quickly called this behavior “unacceptable” and said it should “never be possible”. Huh. It’s hard to imagine how we’re going to empower AI to edit databases and do real work without having at least the possibility that it’s going to go wrong.

Just yesterday, AWS announced General Availability for a cool new service called Aurora DSQL – from the outside, it looks like a SQL database, but it is fully serverless, meaning that you never have to think about managing database instances, you pay for what you use, and it scales automatically and seamlessly. That’s cool, but what’s even cooler? It’s written 100% in Rust – and how it go to be that way turns out to be a pretty interesting story. If you’d like to read more about that, Marc Bowes and I have a guest post on Werner Vogel’s All Things Distributed blog.

Today is the 10th anniversary of Rust’s 1.0 release. Pretty wild. As part of RustWeek there was a fantastic celebration and I had the honor of giving some remarks, both as a long-time project member but also as representing Amazon as a sponsor. I decided to post those remarks here on the blog.

“It’s really quite amazing to see how far Rust has come. If I can take a moment to put on my sponsor hat, I’ve been at Amazon since 2021 now and I have to say, it’s been really cool to see the impact that Rust is having there up close and personal.
