You should actually read the paper. N size of 16. Only 1 of which had used cursor more than 40 hours before. All people working in existing code bases where they were the primary author.

I did read the paper, and the HN discussion (which is how I found it). I recommend you read that, your comments were addressed.

Which of bjclark's specific points does the thread actually refute?

So even if it’s not an actual productivity booster on individual tasks, perhaps it still could reduce cognitive load and possibly burnout in the long term.

Either way, it’s a tool that devs should feel free to use or not use according to their preferences.
