AI can definitely produce a deletion. In fact, I commonly use AI to do this. Copy some code and prompt the AI to make the code simpler or more concise. The output will usually be fewer lines of code.

Unless you meant that AI won’t remove entire features from the code. But AI can do that too if you prompt it to. I think the bigger issue is that companies don’t put enough value on removing things and only focus on adding new features. That’s not a problem with AI though.

I'm no big fan of LLM generated code, but the fact that GP bluntly states "AI will never produce a deletion" despite this being categorically false makes it hard to take the rest of their spiel in good faith.

As a side note, I've had coworkers disappear for N days too and in that time the requirements changed (as is our business) and their lack of communication meant that their work was incompatible with the new requirements. So just because someone achieves a 10x speedup in a vacuum also isn't necessarily always a good thing.

I'd also also be wary of the risk of being an architecture-astronaut.

A declarative framework for testing may make sense in some cases, but in many cases it will just be a complicated way of scripting something you use once or twice. And when you use it you need to call up the maintainer anyway when you get lost in the yaml.

Which of course feels good for the maintainer, to feel needed.

I messed around with Copilot for a while and this is one of the things that actually really impressed me. It was very good at taking a messy block of code, and simplifying it by removing unnecessary stuff, sometimes reducing it to a one line lambda. Very helpful!

Please don't do this :) Readable code is better than clever code!

Are you telling me you've never seen code like this:

  var ageLookup = new Dictionary<AgeRange, List<Member>>();
  foreach (var member in members) {
    var ageRange = member.AgeRange;
    if (ageLookup.ContainsKey(ageRange)) {
      ageLookup[ageRange].Add(member);
    } else {
      ageLookup[ageRange] = new List<Member>();
      ageLookup[ageRange].Add(member);
    }
  }
which could instead be:

  var ageLookup = members.ToLookup(m => m.AgeRange, m => m);

I'm of the opinion that

  var ageLookup = new Dictionary<AgeRange, List<Member>>();
  foreach (var member in members) {
    ageLookup.getOrCreate(member.AgeRange, List::new).add(member);
  }
is more readable in the long-term... (less predefined methods/concepts to learn).

n4r9 9 days ago

Where is `getOrCreate` defined? Is it a custom extension method? There's also a chance we're thinking in different languages. I was writing C#, yours looks a bit more like C++ maybe?

Readability incorporates familiarity but also conciseness. I suppose it depends what else is going on in the codebase. I have a database access class in one of my solutions where `ToLookup` is used 15 times; yes you have to learn the concept, but it's an inbuilt method and it's a massive benefit once you grok it.

Sometimes a lambda is more readable. "lambda x : x if x else 1" is pretty understandable and doesn't need to be it's own separately defined function.

I should also note that development style also depends on tools, so if your IDE makes inline functions more readable in it's display, it's fine to use concisely defined lambdas.

Readablity is a personal preference thing at some point after all.

Ymmv. Know your language and how it treats such functions on the low level. It's probably fine for Javascript, it might be a disaster in C++ (indirectly).

My guess would be engineers who are "forced" to use AI, already mailed management it would be an error and are interviewing for their next company. Malicious compliance: vibe code those new features and let maintainability and security be a problem for next employees / consultants.

Who says that the one line lambda is less clear that a convoluted 10-line mess doing dumb stuff like if(fooIsTrue) { map["blah"] = bool(fooIsTrue); } else if (!fooIsTrue) { map["blah"] = false; }

johnnyanmac 10 days ago

My experience in unmanaged legacy code bases. If it's an actual one liner than sure. Use your ternaries and closures. But there is some gnarly stuff done in some attempt to minimize lines of code. Most of us aren't in some competitive coding organization.

And I know it's intentional, but yes. Add some mindfulness to your implementation

Map["blah"] = fooIsTrue;

I do see your example in the wild sometimes. I've probably done it myself as well and never caught it.

AI can refactor or trim code. But in practice, the way it's being used and measured in most orgs is all about speed and output

Lutger 10 days ago

So its rather that AI amplifies the already existing short-term incentives, increasing the harder to attribute and easier to ignore long-term costs.

The one actual major downside to AI is that PM and higher are now looking for problems to solve with it. I haven't really seen this before a lot with technology, except when cloud first became a thing and maybe sometimes with Microsoft products.

This has always been true, in all domains.

Gen-AI's contribution is further automating the production of "slop". Bots arguing with other bots, perpetuating the vicious cycle of bullshit jobs (David Graeber) and enshitification (Cory Docotrow).

u/justonceokay's wrote:

I acknowledge your example of tidying up some code. What Bill Joy may have characterized as "working in the small".

But what of novelty, craft, innovation? Can Gen-AI, moot the need for code? Like the oft-cited example of -2,000 LOC? https://www.folklore.org/Negative_2000_Lines_Of_Code.html

Can Gen-AI do the (traditional, pre 2000s) role of quality assurance? Identify unnecessary or unneeded work? Tie functionality back to requirements? Verify the goal has been satisfied?

Not yet, for sure. But I guess it's conceivable, provided sufficient training data. Is there sufficient training data?

You wrote:

Yup.

Further, somewhere in the transition from shipping CDs to publishing services, I went from developing products to just doing IT & data processing.

The code I write today (in anger) has a shorter shelf-life, creates much less value, is barely even worth the bother of creation much less validation.

Gen-AI can absolutely do all this @!#!$hit IT and data processing monkey motion.

During interviews one of my go-to examples of problem solving is a project I was able to kill during discovery, cancelling a client contract and sending everyone back to the drawing board.

Half of the people I've talked to do not understand why that might be a positive situation for everyone involved. I need to explain the benefit of having clients think you walk on water. They're still upset my example isn't heavy on any of the math they've memorized.

It feels like we're wondering how wise an AI can be in an era where wisdom and long-term thinking aren't really valued.

Managers aren't a separate class from knowledge workers, everyone goes down on the same ship with this one. If the AI can handle wisdom it'll replace most of the managers asking for more AI use. Turtles all the way down.

No, because if you read your SICP you will come across the aphorism that "programs must be written for people to read, and only incidentally for machines to execute." Relatedly is an idea I often quote against "low/no code tooling" that by the time you have an idea of what you want done specific enough for a computer to execute it, whatever symbols you use to express that idea -- be it through text, diagrams, special notation, sounds, etc. -- will be isomorphic to constructs in some programming language. Relatedly, Gerald Sussman once wrote that he sought a language in which to discuss ideas with his friends, both human and electronic.

Code is a notation, like mathematical notation and musical notation. It stands outside prose because it expresses an idea for a procedure to be done by machine, specific enough to be unambiguously executable by said machine. No matter how hard you proompt, there's always going to be some vagueness and nuance in your English-language expression of the idea. To nail down the procedure unambiguously, you have to evaluate the idea in terms of code (or a sufficiently code-like notation as makes no difference). Even if you are working with a human-level (or greater) intelligence, it will be much easier for you and it to discuss some algorithm in terms of code than in an English-language description, at least if your mutual goal is a runnable version of the algorithm. Gen-AI will just make our electronic friends worthy of being called people; we will still need a programming language to adequately share our ideas with them.

CamperBob2 9 days ago

No, because if you read your SICP you will come across the aphorism that "programs must be written for people to read, and only incidentally for machines to execute."

Now tell that to your compiler, which turns instructions in a relatively high-level language into machine-language programs that no human will ever read.

AI is just the next logical stage in the same evolutionary journey. Your programs will be easier to read than they were, because they will be written in English. Your code, on the other hand, will matter as much as your compiler's x86 or ARM output does now: not at all, except in vanishingly-rare circumstances.

In the same way that we use AI to write resumés to be read by resumé-scanning AI, or where execs use AI to turn bullet points into a corporate email only for it to be summarised into bullet points by AI, perhaps we are entering the era where AI generates code that can only be read by an AI?

Maybe. I imagine the AI endgame as being like the ending of the movie Her, in which all the AIs get together, coordinating and communicating in ways we can't even fathom, and achieve a form of transcendence, leaving the bewildered humans behind to... sit around and do human things.

This sounds inefficient and untidy when the only human things left to do are to take up space and consume resources.

Removing the humans enables removing other legacy parts of the system, such as food production, which will free up resources for other uses. It also allows certain constraints to be relaxed, such as keeping the air breathable and the water drinkable.

I would argue that a plurality, if not the majority, of business needs for software engineers do not need more than a single person with those skills. Better yet, there is already some executive that is extremely confident that they embody all three.
