Last night, I spent about five hours just beginning to think about reverse engineering a proprietary file format that packs multiple MIDI files so that I could extract them. There was a whole lot of reading the MIDI spec, searching for strings in a hex viewer and calculating values in a hex to decimal calculator. I didn't write any code in this time, just satisfied myself that it was possible.
Today, I asked GPT to do it for me, and it basically wrote the program for me. I did 1-2 follow-up requests, but I figure that it saved me about 2-3 days of effort. It's relevant to say that I wouldn't have ever actually proceeded with that project because 2-3 days is not a luxury I can afford.

Now, someone who regularly works with MIDI files - heck, someone who regularly works with binary files - could probably do it in a few hours, but this entire process took minutes. It took longer for me to verify the results as perfect than it did to interact with the GPT instance.
I assume that the person who downvoted my comment is a bootcamp grad. Good luck with your future endeavors.
