I'm a bit scared for what this means as I don't think being able to faster write boilerplate is something worthwhile. The example ed_elliott_asc made is one of those examples where instead of fixing things so you don't have to repeat yourself, copilot makes it easy to just live with the boilerplate instead.
But do you believe people being slower at writing boilerplate is undesirable?
Boilerplate generally exists for a reason, and it's not because the creator likes typing.
