After I spend a couple of weeks with Copilot I must say it works more or less as advertised (the exceptions are funny though) and there is no comparable product in sight. In the business of development tooling this is probably a feature not to miss in the long run if you prefer to stay in said business.
I realize there is Copilote integration for JetBrains IDEs as well. But it's one thing to have access to a resource. And another to have control over it.
