      you can just be (ideas men ). people who only have ideas without any programming skills. can make character skins in the game. just by entering the picture and prom. and gpt chat will create the game character skin program in 3 seconds. (a game where everyone can use different characters, clothes and looks)

    The difference is that you knew what to do and this is why it worked. It is a nice tool but it is like giving a modern tool to all guys living in middle ages. And still as a cloud data eng. I do a lot of work with low code tools and the development part is about 10 - 20% of my working time. It is all about thinking what is better and testing different solutions. It is about discussing requirements within team and designing solution.

      I've seen a lot of people say similar things and you may be right, but I can't help but think it's just a way to cope with the fact that it could make a lot of our jobs obsolete.
      Sure the ai can't do a lot of the "human-like" deep thinking stuff, right now at least, but I think the question is does that even matter when it takes so little time to talk to the ai and let it help you make difficult decisions plus give you the code for it. And almost anyone can do that with just a little bit of knowledge,. So sure, maybe a small amount of engineers will still be needed to run the AIs, just something to think about.

    I have been an average student my entire life the country I live in doesn't have many job prospects I know the fundamentals of programming languages and I love it. But this chat GPT scenario is really very depressing to me I'm afraid that if it'll eat up jobs of 20 to 80% of the workforce I'll surely be on the list since I'm average. Can you please advise am I being nihilistic/pessimistic or it's the hard truth. Any comment from your side would mean the world to me.

      It is a very powerful tool and it will give you a lot more opportunity if you use it right. It cannot just build something without being asked to do it and being given a starting point. Use your creativity to come up with an idea as an app or otherwise then use chatgpt to accelerate the design and development. It works as your business analyst, your architect and developer. It builds something and you suggest improvements and manage the development. It needs to be guided otherwise it doesn’t work.

      Programming is the job most obviously at risk of being eliminated by a productive computer program. The job of programming is going to be shifted to managing AI software which will likely be the thing to write all other programs on command -- maybe a programmer will review the code before anything is launched but the job will become something like an editor rather than a manufacturer and the number of programmers required for a project will be cut significantly.
