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.
In a perfect world we’d all have excellent comprehensive metaprogramming facilities in our programming languages and no incidence of RSI (e.g. carpal tunnel syndrome). Code completion is a good tool to deal with these realities.
