Agreed. It knows what something is supposed to do fairly well.
co-pilot excels in writing tests. It removes so much of the tedium and boilerplate. It seems to understand fixtures once you define one and understands subsequent changes to the boilerplate such as changing usernames, ids, appending items to lists. It is such a massive boost in productivity that those using it are way ahead of those who resist.
That's great. I've done something much similar with other tools. It certainly helps automate the drudgery in writing tests for code that I understand and wrote.
