They should be related to a #language#technology task, able to be automatically evaluated, with training and test #data able to be distributed to participants at low- or no-cost, and should be fun!
I just finished a productive Copilot session on a complex programming task. I came up with much of the algorithms, and wrote a lot of the code, and had to guide it a lot throughout, but credit where due, Copilot did make small but meaningful contributions along the way.
Overall, not a pair programmer but someone useful to talk to when WFH alone on complex tasks.
Enough for Copilot to earn a ✋🏽. And I like how it responded to that. It has got that part down. 😉
