Soon we will see the guys who create these scammy fake Upwork profiles use this to generate the code for their clients and pocket the almost 100% profit margin!
The people I hire through Upwork don't deliver code raw through a chat... They deliver working solutions, of which code is one part.
If they want to build the solution with ChatGPT, then all the more power to them! I doubt they will get 100% profit margin, since they will have to parse my requirements and deliver a working system with multiple parts, which is a lot of the work nowadays.
On a tangential point, if ChatGPT and other AI-assisted methods really deliver, it will likely be more beneficial for many consultants and agencies to do fixed or value pricing rather than hourly, and most value will be concentrated around business analysis / architecture / design stuff. I personally this is a good thing; in my personal experience I've found the best margins doing that stuff rather than pure implementation.
What a time to be alive!
