Kerrick commented on LLMs as the new high level language federicopereiro.com/llm-h... · Posted by u/swah

I am only seeing that if the person writing the prompts knows what a quality solution looks like at a technical level and is reviewing the output as they go. Otherwise you end up with an absolute mess that may work at least for "happy path" cases but completely breaks down as the product needs change. I've described a case of this in some detail in another comment.

That is exactly what I recommend, and it works like a charm. The person also has to have realistic expectations for the LLM, and be willing to work with a simulacrum that never learns (as frustrating as it seems at first glance).

You do? Deno is maybe a single digit percentage of the market, just hyped tremendously.

> E.G. compare tsx versus Node's native ts execution

JSX/TSX, despite what React people might want you to believe, are not part of the language.

It only doesn't work in some contexts due to legacy reasons. Otherwise it's just elaborate syntax sugar for `Promise`.

Similarly: TypeScript, despite what Node people might want you to believe, is not part of the JavaScript language.

The only logical end of this is that they should ban 3d printers and cnc mills to unlicensed individuals. Which, is probably the goal. Things like 3d printers, drones, GPUs, general purpose computers, vpns, encryption, talking to people in private and the like are far too dangerous for the citizenry to be allowed to do without appropriate oversight and approval.

Are these software popular? Are these maintainable long term? Are you getting feedback from users?

Kerrick · 8 days ago

RatatuiRuby is pretty new still: its beta launch was Jan 20. Octobox's TUI is built on it [0], and Sidekiq is using it to build theirs [1].

I believe they'll be maintainable long-term, as they've got extensive tests and documentation, and I built a theory of the program [2] on the Ruby side of it as I reviewed and guided the agent's work.

I am getting feedback from users, the largest of which drove the creation of (and iteration upon) Rooibos. As a rendering library, RatatuiRuby doesn't do much to guide the design or architecture of an application. Rooibos is an MVU/TEA framework [3] to do exactly that.

Tokra is basically a tech demo at this stage, [4] so (hopefully) no users yet.

> No more AI thought pieces until you tell us what you build!

Absolutely agree with this, the ratio of talk to output is insane, especially when the talk is all about how much better output is. So far the only example I've seen is Claude Code which is mired in its own technical problems and is literally built by an AI company.

> Write your own code without assistance on whatever interval makes sense to you, otherwise you'll atrophy those muscles

This is the one thing that concerns me, for the same reason as "AI writes the code, humans review it" does. The fact of the matter is, most people will get lazy and complacent pretty quickly, and the depth of which they review the code/ the frequency they "go it alone" will get less and less until eventually it just stops happening. We all (most of us anyway) do it, its just part of being human, for the same reason that thousands of people start going to the gym in January and stop by March.

Arguably, AI coding was at its best when it was pretty bad, because you HAD to review it frequently and there were immediate incentives to just take the keyboard and do it yourself sometimes. Now, we still have some serious faults, they're just not as immediate, which will lead to complacency for a lot of people.

Maybe one day AI will be able to reliably write the 100% of the code without review. The worry is that we stop paying attention first, which all in all looks quite likely

Those of us building are having so much fun we aren't slowing down to write think pieces.

I don't mean this flippantly. I'm a blogger. I love writing! But since a brief post on December 22 I haven't blogged because I have been too busy implementing incredible amounts of software with AI.

Since you'll want receipts, here they are:

Between Christmas and New Year's Day I was on vacation, so I had plenty of time. Since then, it's only been nights & weekends (and some early mornings and lunch breaks).

> Friction_cost is the energy lost to errors, retries, and misunderstandings when actually using the tool. [...] if the tool is very low friction, agents will revel in it like panthers in catnip, as I’ll discuss in the Desire Paths section.

This is why I think Ruby is such a great language for LLMs. Yeah, it's token-efficient, but that's not my point [0]. The DWIM/TIMTOWTDI [1] culture of Ruby libraries is incredible for LLMs. And LLMs help to compound exactly that.

For example, I recently published a library, RatatuiRuby [2], that feeds event objects to your application. It includes predicates like `event.a?` for the "a" key, and `event.enter?` for the Enter key. When I was implementing using the library, I saw the LLM try `event.tilde?`, which didn't exist. So... I added it! And dozens more [3]. It's great for humans and LLMs, because the friction of using it just disappears.

EDIT: I see that this was his later point exactly! FTA:

> What I did was make their hallucinations real, over and over, by implementing whatever I saw the agents trying to do [...]

[0]: Incidentally, Matz's static typing design, RBS, keeps it even more token-efficient as it adds type annotations. The types are in different files than the source code, which means they don't have to be loaded into context. Instead, only static analysis errors get added to context, which saves a lot of tokens compared to inline static types.
