<p>the ur-text behind this piece is: people just not understanding exponential capability growth. including the author of the piece!<p>if you could look clearly at the progress from 2020 to 2023, as someone like Gwern did, and from 2023 to 2024 with the invention of reasoning modes, then it was not that hard to understand what would happen in late 2025. Opus 4.5 was not a surprise to anyone who was actually paying attention.<p>But people (including the author) still mistake the current state as a stable state and future gains as incremental. he says<p>“I am not asserting that all code will eventually be AI-generated to spec, bypassing human understanding”<p>I AM asserting that, and it’s incredibly easy to do so.<p>The question of “when” is separate.</p>

<p>At Oblong Industries one of the basic building blocks of everything we built was a homegrown C-based IPC system called Plasma. The message channel was an mmap'd file used as a ring buffer. All messages were human-readable, performance was good, configuration was trivial.<p>What was especially useful (and unusual in IPC systems it seems) was the property that message channels  outlive all readers and writers, and even survive reboots, because they're just files.  For local IPC you don't need a broker or server process.<p>All the engineers who ever worked at Oblong loved Plasma, so I've recreated and updated it, as Plasmite.<p>It's written in Rust and the message format is JSON, but it's fast because it's based on lite3 (<a href="https://lite3.io/index.html" rel="nofollow">https://lite3.io/index.html</a>), a really cool project you should also check out.<p>Bindings for Python, Go, Node, and C, but you can also get a lot done with just the CLI tools.  The basic commands are 
- "feed" (to write)
- "follow" (to tail)
- "fetch" (to read one)
- "duplex" (to have a 2-way session)<p>I think duplex could be great for agent-agent communication, but I haven't tried this much yet. If you do, let me know!</p>

<p>Even with agentic coding there's a lot of merit in keeping a strong distinction between your specs (TDD, architecture, etc.) and your backlog (your sequence of work items).<p>Backlogs are better off being represented as a task dependency graph, rather than a heap of markdown files, because a nice graph of tasks:<p>- helps agents focus
- gives better observability of partial progress
- supports parallelization better
- works well with subagents<p>Also, the act of planning a backlog *makes the design better* because in the act of planning, you learn things about your own design. This is as true for agents as it is for humans.<p>The planning modes of claude and codex blur the distinction between specs and backlog and land you in a heap of markdown files.<p>Steve Yegge diagnosed all this, and his solution was the beads CLI -- a brilliant idea. You just tell your agent to use this CLI for planning instead of their own plan mode (all you do is add a one-liner in your AGENTS.md file), and you get an instant planning upgrade.<p>However, I found the implementation of beads a little bit hairy and flaky, when I tried to use it in production. And the performance made me sad.<p>So I've reimplemented the core concepts, as ergo.<p>It's very fast (5-15x faster than beads), very robust, and rigorously simple. There is no daemon running, no SQL database, it's self-healing, and the plans are stored as JSONL, so if all else fails you can just reconstruct your plans from scratch.<p>Implementation:<p>- Plans live in `.ergo/` in your repo root (or your dir of choice). JSONL was chosen because it's git-friendly & easy to resolve merge conflicts around.
- ergo is concurrency-ready if you're into agent swarms.
Concurrent writes are serialized with flock(2). Multiple agents can race to claim tasks — exactly one wins, others fail fast.
- Do operations in huge plans of 1000+ tasks in ~15ms on a Macbook Air.
- The help text doubles as the agent manual. I spent a lot of time on `ergo --help` and `ergo quickstart` because they're the primary interface for agents.<p>I've been using ergo heavily for a couple months and I believe it's solid enough for anyone to use, would love your feedback.</p>

<p>A lot of folks here are making some version of the observation that an immutable public unforgeable database is, in practice, equivalent to ANY database which is sponsored by the state. That feels persuasive to me.<p>Does this imply that the blockchain ledger might have greater utility in areas where there is weak or no state control? Basically, the criminal underworld and black markets. What's been written about this?</p>

<p>I don't think it's wild Silicon Valley chatter to say that public transportation along fixed routes WILL decline as a result of new technology, and this is a great thing.<p>Fixed-route 19th-20th century public transportation networks are inefficient because most of the vehicles are pretty empty most of the time. This makes these systems expensive on a passenger-per-seat-mile basis. Not to mention the colossal waste of people's time spent trying to accommodate their journeys to those fixed routes (and schedules).<p>Example: LA's Metro system is subsidized to the tune of about 50 cents per passenger seat/mile, or was as of 2009 (<a href="http://www.newgeography.com/content/002361-los-angeles-metro-bus-system-compares-favorably-with-its-peer-group" rel="nofollow">http://www.newgeography.com/content/002361-los-angeles-metro...</a>)<p>In 10-15 years, transport companies like Lyft/Uber/Didi will be able to offer municipalities a much better deal than that. An electric car or van without a driver in it, with an operating lifetime of a million miles, will cost on the order of 20-40 cents a mile to run. Get 3-8 paying customers into the vehicle, and there is absolutely no need for a 50 cent per passenger seat mile subsidy.</p>

<p>Agree!  In my experience successful remote work is associated with 2 things:<p>1. extremely well defined problem domains<p>2. incrementalism<p>For lots of engineers, those 2 points describe their job. Lots of (incremental) value is created that way.<p>But I'd argue that the larger gains accrue to those companies -- or those cities -- where work is being done in non-well-defined problem domains. And not incrementally, but by big leaps, experiments, and messy failures.<p>In fact, you could go farther and argue that in a competitive landscape, companies will quickly match each other in their performance in well-defined problem spaces, and the only way to actually compete at the margins is in problem areas that are, by definition, newer and not well defined.</p>

<p>For this reason, I wear a helmet.  But the health benefits of cycling vastly swamp the risk of death, so the helmet gain is only a small marginal difference.<p>The person who is truly taking a risk is the person who doesn't ride a bike because of the perception that it's dangerous, and continues to be sedentary and drive a car to work. This person is literally reducing their life expectancy by years. (See links I posted elsewhere in the thread.)<p>You need to be able to think about conditional probability.</p>
