> A problem with this is that in order to confirm the findings, you’ll need an expert human. But generally expert humans are busy doing other things.

The article suggests using LLMs to identify and fix UB. However as per the above, I think the issue is that we need more expert humans.

LLM generated code will eventually contain UB.

EDIT: added "eventually"

> Correctness: 1,778 test cases from the official jsonata-js test suite + 2,107 integration tests in the production wrapper.

The AI generated code can still introduce subtle bugs that lead to incorrect behaviour.

One example of this is the introduction of functions into the codebase (by AI) that have bugs but no corresponding tests.

EDIT: correct quotation characters

What was the interesting problem that Swiss watchmakers could have focused on, instead of pursuing brand?

How do I market myself as a freelance Backend/Infrastructure engineer?

I've been on the contract market for a few weeks now.

Apart from submitting my Resume, are there any other proactive things I can do to increase my chances of landing a contract?

For example frontend developers can create portfolios; I'm not sure what the equivalent would be for backend/infra people.

Please can you elaborate? We are more intersted in "the end" in what sense?

Is "AI code review" a correct term?

A code review requires reasoning and understanding, things that to my knowledge a generative model cannot do.

Surely the most an AI code review ever could be is something that looks like a code review.

I also worry about a centralised service having access to confidential and private plaintext files of millions of users.

Often when I look closely at the output of LLM generated code, I see repetition, redundant logic and deeply hidden bugs.

Notwithstanding the above, to my understanding LLM services are currently being sold below cost.

If all of the above is true, at some point the degredation of quality in codebases that use these tools will be too expensive to ignore.

These LLM tools appear to have an unprecedented amount of access to the file systems of their users.

Is this correct, and if so do we need to be concerned about user privacy and security?

My understanding was that atherosclerotic plaques are comprised of cholesterol or fatty deposits [1] and that these can lead to CVD.

The fat mechanism I understand, but what is the mechanism for sugar in CVD?

Is cost a risk here? I'm assuming that sometime in the future the price for vibe coding/engineering will go up significantly.

I have noticed that many of the most used and loved projects use C/C++.

With all of the unpopular press that they get, why has history often proven C/C++ to be the right choice time and time again?

I thought this was going to be an essay on the impact of English, Math and Programming on humanity.

I would place English (or all spoken/written languages in general) first, Math (as discovered) second, and programming languages last.
