Yes, but it is still much faster than a person could perform the task. Replacement is not simply about "it can do your entire job now." Replacement also occurs when a tool can be used by someone to produce much more work output than previously. If one person can use this tool to produce what used to take five people, guess what? 80% of the work force for that project just got "replaced." Yes, high skilled professionals are still needed in this instance to guide and monitor the AI, but many fewer of them than previously.

I copied the transcript into chat gpt 4 and had it summarize the video: "In this video, Nick uses the new GPT-4 model to refactor a legacy codebase in C#. The AI model successfully refactors the code based on the given principles, such as SOLID, KISS, YAGNI, and DRY. It generates an interface, a user repository, and a validator, among other changes. The AI also helps address issues with the constructor and suggests using an IClock interface for dependency injection. The refactored code compiles successfully in the IDE. This demonstrates the potential for AI tools like GPT-4 to assist developers in refactoring legacy codebases and improving overall code quality." - chat gpt 4

@@zolniu Yeah the curve is log(n). Plus there is the thing that it can't think for itself. And we're a long shot from that one. It can maybe act like it's thinking by itself but it's not actually doing it. Edit: for the emotional and easily butthurt people: the following is a very simplyfied example for the sake of explaining how AIs do not understand things, while they have deductive reasoning, and can draw the conclusion of the following example. I mean what this is a huge data storage that basically memorized the internet. It can tell you what 2+2 is. It can tell you why 2+2=4. But it doesn't understand it. Like a Person who just memorized that 2+2=4 because 1+1=2 and 1+1+1+1=4. For the lack of a better and still easy to understand example: If it never learned what 2*2 is, it wouldn't know the answer is 4. Even though it memorized that 1+1=2 but can't get to the solution by just doing that calculation again and put it together => 2*2. A human is capable of that, AI is not. An AGI might be. But then again, fair to say, humans aren't able to memorized the entire internet.

[@Beltalowda55]

Wow, this is seriously impressive. I just keep thinking how great it will be to offload most of the grunt work. Remember, this is a "general" chat bot. Future versions coming very soon will be code specific AI toolsets integrated into IDEs and command line utils (CD/CI pipelines, etc.) that can run locally to keep code private and to learn company/domain specific information. This is such a productivity boost. Automatic refactoring, testing, PR reviews, etc... Yes, there will be some "issues" along the way, but I suspect those "issues" will be addressed very quickly. The rate that this progressing is mind blowing. Probably because of the insane productivity of the AI developers that are using their own tools. 😁 My head is swimming with all of the possibilities. I don't think it will replace devs completely, but there will be much less of us and the job itself will change quite a bit.

[@Lethcode]

I think there is plenty of work for software teams still but I think you will get by with less people per team. Still need security reviews, someone to actually read the code generated and test interactions with other projects. For simple programs you won't need a developer. It will be interesting when it starts consuming open api end points and you can tell it to wire up specific calls so you can just build the guts

That being said I can already see some disasters that this tool will produce. a/ basically sharing your codebase with the engine - breaking most of security protocols in the company b/ Dunning-Kruger effect amplified for junior devs - which can cause disasters for the company in the long run, when things start falling apart c/ possible worse treatment by other non-dev employees in the company - but if this tool gets good enough, you can easily ditch the company and start your own, since you will be efficient like a team of 10, but without all the communication/management/cost issues.

4:14 Another way to refactor that is to create a seam there, a protected virtual method that internally call the static method, "Extract and Override" and when testing you can create a Testable class which overrides it and does not call anything, logs or validates depending on whether you want a stub, a spy or a mock. For those juniors watching this video: note that the initial solution was wrong, the next one too, and that it took some time of back and forth to get with a correct one.

The one to seems work best is "refactor according to the guidelines of the book Clean Code" (can tack on SOLID as well). Its really hard to make it really break down everything down into small methods but that one is the most efficient I found. Uncle Bob is the Greg Rutkowski of coding :) . "Write extension methods covering all if-statements" is also a good one

Now in the past I coded databases in dBase III and IV for bookkeepers, but I forgot a lot, but I recognize the strings that are used, not in JS specific, but I used it already to code a playlist database in SQL. It's great stuff what it can do. And a good refresher for my memory. Great channel BTW.

I did the same and it was great. Nothing super complicated but it helped me refactor an Azure Function that was long running into a fan out/in durable orchestrator function calling activity functions. I then asked it if the system could handle 10k requests a second just for fun even though obviously that's a heavy load. It gave me a very thorough list of everything I needed to do to ensure the best scalability and performance.. bottlenecks, rate limits, db, parallelism in functions, etc. Developing with GPT-4 is a delight so far. It feels like having a teacher and a coder working for you at the same time.

Comment written by AI, because I'm lazy... (I'm amazed that it could create a working regex from the mess I gave it 🤯) Hey everyone! I recently used ChatGPT-4 to help me extract and format data from a messy lunch menu HTML text. I described my problem to ChatGPT-4 and it provided me with JavaScript code snippets that addressed my concerns. Throughout the process, I was able to give feedback and request improvements, and the AI was incredibly responsive. In the end, we created a well-structured lunch menu object from the HTML text, which included all the necessary information for each weekday. I'm truly impressed by how ChatGPT-4 made this process so much easier and efficient. It felt like having a coding buddy by my side. Can't wait to use it for more projects in the future!

[@carldaniel6510]

Nice demo! I think refactoring is one of the most straightforward and useful applications for models like GPT. While I would expect a senior developer to have been able to do this refactoring in only a few minutes, the fact is, as you pointed out, many could not, and less senior developers might never get there, even with a lot of prompting. This and the use as a more interactive form of documentation (e.g. "show me how to use the lag function in SQL") should be integrated into development environments ASAP. These kinds of tool free up congitive space in the brains of developers to actually spend their time developing, and less time going through the mechanics of typing and retyping code.

[@cmilkau]

For me, this is like the first time I got to interact with a computer. There's this extremely powerful and versatile tool, and you just want to see what you can achieve with it. That's what got me into coding. I don't understand the fears of "getting replaced" at all. It's not like there is nothing to do for software companies. And with these kind of tools, cost should go down, which may create even much more demand. I mean, in the long run probably every profession will undergo some decline, being replaced by new professions. For one, that's not around the corner in software. Two, who says we can't do those new professions? Three, that would probably be an upgrade as well.

What I realized by watching it refactor code is often I've made "design patterns" in my code but not the standard type but my own sort of designs. ChatGPT has had me recently refactoring a lot of my code I'm making now into injectable design patterns so the "future version" (if there is one on a prototype) is a lot cleaner.

[@chadknudson]

I think the best way to harness the power of ChatGPT as a mid-level engineer is to use it to help you in your daily tasks and to view its results with a critical eye, in the same way you would do when conducting a code review. As you saw in the video, it isn't going to get things 100% correct and optimal each and every time. It relies on you to guide it down the path of finding the correct solution. You can ask ChatGPT to produce explanations for you which when you ask it to produce or refactor code for you so that you can use it as a learning tool. You can ask for citations for the decisions that are made and go to those source materials to learn about the underlying concepts.

Since this is a known interview question, there are probably several pages on the net explaining how to do that specific example. As such, the example and how to solve it is probably part of the training data for the AI model. It would be really interesting to see how it does on an example that it hasn't seen before. From what I have seen and tested of ChatGPT (although the older model), if you challenge it on something it quickly agrees with you, even if your challenge is actually wrong. If you do make a follow-up to this video, making it motivate its decisions (such as not correcting the spelling or "firname") would be really interesting to see.

It would be hard to know exactly what datas have fed GPT, but can't we imagine an very unusual code base (something it is very unlikely to have learnt) to refactor instead ?

[@_FLOROID_]

If it's an interview question then GPTs responses aren't indicative of real-world performance as it has likely seen this task or similar tasks before in its training dataset. Often times when I actually try to use it at work it utterly fails across the board. As soon as I could find a simple solution online for a refactoring problem - it gives better answers.

[@watherby29]

No wonder it writes good code. It learned from senior devs code. I am waiting for it to be creative before I become a plumber.

[@enriqueflorendo]

If code is in folders, how would you feed it that?

That credit limit check < 500 should have been put in the credit limit provider so that it can be tested

[@LuckyLukas90]

can someone explain me what was the problem with the DateTime.now approach? unfortunately i didn't understand it in the video.

[@nickchapsas]

[@MaxQuagliotto]

@@nickchapsas So the problem is not the code itself, it's just the testability of the code that's the problem.

[@MaxQuagliotto]

@@mhoertnagl any time the method is called shouldn’t Datetime.Now always pull the time from system clock regardless of lifetime of the validator class? I figured the real issue is that for unit testing you always want to have the same result which DateTime.Now inherently cannot produce

[@devnami]

What's your opinion on ChatGPT and it being replacing the devops jobs? Do you think that's a possibility in near future? Is it going to happen?

[@ihatethesensors]

That was great my reaction was about the same.

[@maxnova9763]

How would this pan out if you give it a problem that isn't an interview question?

[@nickchapsas]

I tried it with more code and it’s still pretty good. The better the questions you ask the better the results you get back

[@ifstatementifstatement2704]

Many question the very validity of OOP for programming in general. It was invented by a marine biologist who wanted to code a program mimicking marine life.

[@user_ahfvjjfb]

This is absolutely amazing and really scary, we're easily replaceable now. GOOD JOB!

[@cmilkau]

Has anyone been replaced yet? The demand for software has not nearly been exhausted. For now, expect more to be done with the same people, not the same with less people

[@nguyenvi_cntt]

oh how great it is

[@RedOneM]

GPT-10 will be able to replace 90%+ of jobs with thought processes. Now once infrastructure is build around robots, there's no much what common people are able to do anymore as a job.

[@BrazenNL]

You know what's also fun? If you get an error (at least, with Rust), you can paste the errors and it'll try again.

[@jurassa9588]

@Nick Chapsas I think you can agree with me that in order to be productive with this thing your have to first master your craft. Give F35 to normal pilot he cannot do much.

[@ManeshBPandu]

Very nice way to use the AI ChatGPT... Noce job by a machine.

[@CiaranGallagher1]

I cannot fathom how this even works.It's insane!

[@JayVal90]

A few decades of helpful programming blog posts as training data really helps, combined with the highly pattern-based nature of the questions being answered (which is precisely what these generative AI's are designed to do well).

[@higherbeingX]

i think i can keep my bartender job for some more time. All the best devs.

[@nidungr3496]

It's not just devs, it's every white collar career. Lawyers, artists, teachers, writers, engineers, architects, office assistants, medical doctors, sales, HR, industrial designers - all of them can and will be replaced by an AI that does their job better, faster and cheaper. Developers just happen to be replaceable by stock GPT-4 while the other sectors require some level of specialized tooling. This is the abrupt end of the 20th century knowledge economy, with even OpenAI predicting 40-50% unemployment within a few years (the Great Depression was 25% at worst) and most likely second order effects such as a collapse of demand for non-industrial blue collar jobs, a massive oversupply of desperate people pouring into manual jobs, bank failures due to large amounts of foreclosures, and all this will be fertile ground for political extremist takeovers or revolutions. (Don't forget that a massive economic crisis was what toppled the Weimar republic.) Good luck bartending, lol.

[@Amitkumar-dv1kk]

How would it perform in competitive coding, like that on the leetcode, they tend to involve complex thinking processes in order to solve them, that would give an estimate of how much thinking does gpt4 actually does. Now i can't test it out myself because I don't have plus membership neither do I wish to, because I don't have it's use right now. chatGPT would fail horribly I know, it had failed for the very trivial of the coding problems for me, so I just want to see how gpt4 would perform.

[@Forshen]

at 04:18 We also have Static code from a dependency code base, so we created a Adapter with the name based on the class with the statis methods, example: "ProductAdapter" and the adapter has the same methods as the static class and the adapter methods just calls the static methods. Is this a good way?

[@nickchapsas]

Yeah it's the same thing. Normally it's called an adapter but you can also call it proxy, forward method or wrapper.

[@Forshen]

@@nickchapsas ah thanks. Still trying to learn differences between design patterns. But proxy, wrapper, adapter and 'forward method' are all the same thing? I thought there was a difference for the proxy tho, never understood it. But now I know, thanks.

[@paulkoopmans4620]

​@@Forshen Technically "Adapter" and "Proxy" are indeed different things. But they do get mixed up a lot of times. But it is all in the names! 1. Adapter (also called wrapper) => A class that implements an interface, or extends from a base or abstract class and 'wraps'/encapsulates another class. The purpose of the adapter class is to implement the "contract" and forward them to the wrapped class. The wrapped class never had the proper interface but your adapter does the right stuff to make it happen. Think the little adapter plugs you use when you travel to a different country; you adapt the one interface to the other; 2. Proxy => a class that implements an interface and encapsulates a class with that same interface. The purpose of the proxy is to add behaviour either before, after or both and 'proxy'/forward it to the encapsulated class. Think a WattMeter; same prong style but the added value is now you are 'logging' traffic.

[@Forshen]

@@paulkoopmans4620 ah well, that makes a lot of sense to be honest. Thanks!

[@iankynaston-richards5239]

I've been able to get Chat GPT to fabricate large amounts of information loosely based on factual data. It was not making the occasional mistake, it was making stuff up in a very believable way.

[@agsystems8220]

Huh, so what happens if you prime one instance of GPT4 to do stuff, and a second to act as an interviewer looking for bugs, and then get them to have a conversation with each other? It seems to be decently aware of it's mistakes in retrospect, so is it possible to get it to do so on it's own? It is massively impressive that it can do that side of the conversation, but could it also provide your side?

[@agsystems8220]

My understanding is that it's "Mind's eye" isn't perfect, so it may actually just work better if you prompt it to do multiple passes rather than expect it to produce something fully formed.

[@gabrielonibudo5566]

Someone needs to try this out ASAP!

[@ztBlackGad]

Hey Nick. Can you try to upload source code to chat as base64 of regular zip and ask it to convert and unzip code. Afterwards refactor? And to receive response ask it to zip and show you base 64 of that thip file?)

[@StefanoGabriele1983]

Is there a service where we can give a solution (.net core or framework) and the AI will refactor it for you or help to find bugs or bad practices?

[@MarkoMijuskovic]

Well,... time to switch to woodworking... always wanted to do something with wood and here is my chance...

[@nhtdmr]

Excellent work. Keep creating videos how to use GPT4 in development and give us tips, tricks, commands to use and samples please.

[@plamenstoyanov5605]

Nick: How scprited this video i want to be? Nick: Yes

[@georgebeierberkeley]

Uh, I'm glad I'm 59 and near the end of my career. If I were 25 I'd have serious anxiety over this. It'll take years to get as good as the machine.

[@georgiosdrosinos9530]

Hey there! It would interesting if you write some tests first, and then let GPT-4 to write the code to pass them.
