Robots Are After Your Job: Exploring Generative AI for C++ - Andrei Alexandrescu - CppCon 2023
github.com/CppCon/CppCon2023
Almost a year since the launch of ChatGPT - considered by many as the first truly compelling code generator that translates free-form human language into code - the C++ community continues to grapple with the implications. Reactions range from indifference or skepticism to genuine concern about the future of human programmers.
Although some advanced C++ techniques are already accessible to tools like ChatGPT, certain fundamental aspects remain outside the reach of current and possibly next-generation generative AI tools. This disparity raises pivotal questions: Which parts of the intricate C++ ecosystem can we confidently delegate to generative AI? What uniquely human skills must we retain and refine?
We'll probe the potential and limits of contemporary AI, taking a novel look at the age-old binary search algorithm. Although this algorithm has long been held up as a paragon of efficiency, we challenge that notion. What would ChatGPT have to say about it, and how might it partner with us to refine this cornerstone of algorithmic logic? The conversation opens a window into a future where developers become the "one percenters" of programming-focusing solely on the most cerebral and high-level challenges, while AI takes care of the everyday tasks. Join us to explore this fascinating paradigm shift and reflect on what it means for your own work in and with C++.

I had the pleasure of picking Andrei's brain for many hours over several days at a conference in Boston several years ago. Fantastic engineer and fantastic person. His talks never disappoint. Thank you, Andrei! I was a little surprised to hear that using a larger left bias for the upper bound portion of the improved equal range algorithm didn't have a benefit. Maybe I need to take a closer look at the implementation and think about the problem a little longer.

This is awesome. This is why I enjoy watching these talks and seeing people continuous question the standards of their own library. showing how these llms can improve your day to day to make the menial tasks easier is a great message to share.

1:08:25 I think that good judgement derives from good intuition, which in turn derives from good skill, which in turn comes from lots of experience. Obviously, a person may not necessarily get stuff from right to level, but that's a different topic. So, no, I wouldn't say that AI levels the playing field in terms of skill.

@CoreDump07 5 месяцев назад

21:20 very well explained, chat gpt and its brothers it not gonna rob us of our jobs, it helps us get better and faster and do more interesting stuff.

It also would be very interesting a talk about using C++ for implementing ChatGPT-like AI... are they using Python for AI nowadays? Why not C++?

@joopie99aa 8 месяцев назад

For equal_range, expanding upon the idea that you're likely to have a small number of equal items (in relative terms), wouldn't it be faster to do an exponential search for the upper bound, instead of a center left binary search? With the center left upper bound binary search, you still start by considering the entire remaining range, but bias towards shrinking it quickly. With an exponential search you start by considering the minimal range and exponentially grow it up to the entire remaining range if necessary. So the runtime of the second part of the algorithm will depend only on the length of the equal range, not on the total length of the list. For large lists in the expected case where the equal range is small by comparison this should provide a significant speed up. Even better, unlike in traditional exponential search, in this case you can 'drag the lower bound (on the upper bound) with you' as you exponentially grow the upper bound. EDIT: ah, I see this was asked in the questions in the end.

@Bolpat 5 месяцев назад

1:25:00 I put the code on slide 36 in GodBolt and with GCC and Clang on O3, there are no mul instructions using int* and std::less. I don’t really understand the assembly, but it contains zero multiplication and zero division instructions.

@eyedl 4 месяца назад

hilarious XD

@Bolpat 5 месяцев назад

1:21:00 the -torae isn’t Latin. It looks like Latin to the uninformed, but it’s not proper. The vocative of nouns ending in _-ore_ is _-ore,_ i.e. the same.

@dmvjjvmd Месяц назад

Well, 3rd declension noun vocatives are identical to the nominative, yes. I'm assuming he went with "programmator" on the analogy of "doctor" (programmatore is Italian), and since he is addressing programmers, it's plural, making the proper form "programmatores" (-es being the 3rd decl. ending nom./voc. pl.). All that said, his name looks Romanian, so perhaps he was riffing off of how Romanian morphology evolved out of Latin. I don't know anything about it.

@muxecoid Месяц назад

Having links to actual prompts used to generate code while iterating would be super helpful. Especially together with discussion of what were the bugs in generated code.

@ivanp_personal 5 месяцев назад

When will we have those algorithms in the namespace std? Did Andrey submit them for standardization? All the best should be part of the standard.

@TheEternalVortex42 2 месяца назад

21:20 this formula doesn't seem correct, you are summing a bunch of integers but then you get a rational number as a value? Even trying n = 2 you get 23/10 which doesn't seem to match what we should get. I think the correct formula is 3 n lg n - 2 n + 2. BTW this shouldn't really take very long even by hand since you just need to know how to sum a geometric series?

@vincentlextrait3092 5 месяцев назад

On average a developer writes 4 lines of code per day. Inserting these faster is not really a thing...

@thesquee1838 5 месяцев назад

Is this a real statistic?

@PikeBot 5 месяцев назад

Exactly. Because you can't trust GPT-generated code, you have to check it. You've transformed a code writing task (the easiest part of your job, unless you're doing something truly unusual, in which case GPT won't have any models to work off of) into a code reading task (much harder, and what most of your work already is).

@tcioaca 5 месяцев назад

Unpopular opinion: not a great talk, sorry (not great doesn't mean it was terrible, though!). Why? It was not balanced (pun not really intended). Instead of choosing such an example and actually insisting so much on that specific problem, for quite a long time threw me off. If the problem requires so much attention to be understood, just to build the motivation of your speech, I am sorry, but this is not a balanced speech, not by the common rules of how most speeches are typically structured. Now, I would have been curious how ChatGPT would have structured the speech, once Andrei had the idea for what the motivation is. Like a meta-production in a certain sense.

@GreenJalapenjo 4 месяца назад

I'm just over half-way in, but so far I have pretty much the opposite impression: it's an interesting talk about algorithms with some kinda unnecessary stuff about ChatGPT thrown in.

@PROMuffy 4 месяца назад

I saw this as a handpicked concrete example demonstrating which aspects of programming AI is currently geared toward and which aspects it has yet to fulfil. The bullet points at the end of the talk summarise these. The talk was as much about how the problem was solved as the solution. Understanding what tools an expert uses and how they use them can give valuable insights into how they work, and then you can consider how that differs from the way you work.

@tcioaca 3 месяца назад

Still, I personally do not think that this is a balanced speech. Maybe he chose the wrong kind of problem. But the structure itself could have been optimized. In the end, is it a speech about the intricacies of a specific algorithm or about what ChatGPT can do for the more common mortal developer!? Why not give examples of more mundane, but not trivial tasks and show when an LLM can help and when it cannot. Sorry, but if for half an hour you expose a complex problem to have to introduce some techniques where ChatGPT can be helpful.. you lost me. Call me stupid, if you will, I stand by my feedback this time.
