It's worth nothing that over the holidays, I decided to pick up Go for a personal project and tried GitHub CoPilot. I was tremendously impressed. At the beginning, it was mostly useful for helping me with syntax as I could ask it to write a for loop, access member variables, etc.

Over time, it would start to suggest larger and larger blocks of code based on what I was writing. It got to the point where it would auto-suggest entire functions based on my code comments. e.g. I'd type: "//Update a user" and it would then suggest complete code for doing just that, while managing to match the style of previous methods, use the correct ORM objects, etc. In general, it seemed to be 90-95% "correct".

However, it did like to remind me that it was just really good at putting words together. For the Update user, it suggested a function that exactly matched how I'd write it, except for this:

//Persist changes to Show object to the database

user.Save()

Just a nice reminder that the GenAI is not "thinking" about what it's doing.
