But I don't want to make the claim lightly, so I did an experiment.
I signed up for copilot pro, and have been using their 'edit' feature. This is more than just their auto complete.
I set myself a goal to create a playable web game of classic frogger.
It took 4 hours with copilot "edit" and my full attention.
I didn't write a single line of code, but I did ask it to refactor and gave it a project description.
I suspect this would have taken me 4 days full time to get to this level.
Try it out:
You could create a Tetris in even less time. Try to create something more novel and less hot on the heatmap of paths walked in gamedev.
