Ok? I'm just explaining what claude code is, not pontificating about the capabilities of AI.

Claude Code is a tool that uses natural language ai systems. It itself is not a natural language ai system.

If they’re reaching the same results across a variety of the most popular public models, it doesn’t seem like that big a deal to know if it was Opus 4 or Opus 4.5

Yea this feels like saying “if you give them good enough specs they’ll produce the code you want” which reduces to…writing the code yourself. Just with more steps.

GH is ripe for a disruptor right now.

I think they're just saying that data extraction tasks are easy to evaluate because for a given input text/file you can specify the exact structured output you expect from it.

Yea, for the vast, vast majority of workloads just forking separate node process ends up being better than mucking with threads.

> they add, remove, refine, change, fix, and break features constantly at that accelerated pace.

I wonder how much of this is because the maintainers are using OpenCode to vibe the code for OpenCode.

When did they get rid of that?

Yes, if you had each programmer rewrite the code from scratch each time you updated the spec.

How is your 2 step process not susceptible to all the exact same pitfalls you listed above?

FWIW modern Rails is fairly magic-free also. They learned. With ActiveJob now part of the framework you get event queues/async processing and whatnot as part of the batteries.

I'm a fanboi, so I am biased, but Rails is still pretty great in 2026 for general business purposes.

Going to systemically turn off your senior staff over time also. Most Senior Engineers aren't that interested in doing even more code review.

Maybe. Businesses have been approaching it this way for at least as long as I've been in the industry (16ish years) and I haven't heard of anyone going bankrupt because of a lack of institutional knowledge.

> Almost all software is unbelievably bad.

This is an opinion. And implies that software would, on average, be better if businesses made more of an effort to retain internal talent vs hire outside talent. And I think that's largely unprovable.

> Seniors come from juniors. If you want seniors, you must let the juniors write the code

The average tenure of a person in engineering role is so short that very few employers are thinking about developing individuals anymore.

The actual way this gets approached is "If you want seniors, you must hire seniors".

I'm not sure how this plays out now. But it's easy to imagine a scenario like the COBOL writers of the last generation.

In the sense that nothing is truly a "proper" hard security barrier outside of maybe airgapping, sure. But containerization is typically a trusted security measure.

> Their lead has not shrunk

It has though, by a lot. Toast in particular has eaten Square's lunch in the restaurant industry and now they're expanding to retail. Even NCR has caught up, along with a long tail of newer competitors eating away at market share.

There was a window of time where Square was the default choice for small biz POS and that is most definitely not the case anymore.
