For me it's only been in the last month with Opus 5.5 that I've been seeing code quality I actually respect (though this is with substantial human effort in the loop). Though this experience is from work where I don't have access to non-Anthropic models, nor Fable.

In the long term, AI writing - mostly done solo, not directed by humans - will likely have higher quality than human writing, while being better suited to people's tastes since it can be personalized for every reader. If so, it's not hard to imagine it crowding out human writing.

You might ask, though, is that a bad thing? If it's legitimately higher quality, then what's wrong with consuming it? Well, I don't know. It certainly seems dangerous for everyone to be in their own little bubble of content. Social media of course tries to do that today, but there are limits. You can't pick any topic, any set of attitudes you want and get an infinite supply of content tailored exactly for you. Even if you find some super niche community to set up shop in, it's still a community; you're still exposed to the outside world at least a little. What happens when that changes?

(This used to come at the cost of code quality, but increasingly does not.)

The main issue with this is that the programs are usually still single-threaded. For some key utilities like find and grep, this has allowed more modern alternatives to leapfrog them in performance. (To be fair, it’s hard to add parallelism without breaking compatibility somewhat.)

But in most other respects, there’s nothing wrong with being a little old-fashioned. Using global variables is an example of that. It’s a problem in larger programs but at this scale it’s fine.

Actually, there’s another exception to my previous statement that I should have mentioned. For mitigations that are meant to prevent an attacker from turning memory corruption into code execution or code-execution-like control – such as restrictions on mapping memory executable (at least that’s one purpose for such restrictions), or memory map lockdown – the mitigations’ effectiveness doesn’t depend on whether they’re applied to children. Those mitigations are sometimes treated as part of the sandbox system, sometimes separate.

If asr can be used to bypass FDA then that is just a security vulnerability.

Though, there is also a third type of Documents directory, the kind located at paths such as ~/Library/Mobile Documents/com~apple~TextEdit/Documents. This is part of iCloud Drive and is the same directory that you get in Finder by going to iCloud Drive -> TextEdit. Very confusing.

But yes, it's unfortunate that macOS sandboxes cannot be nested.
