I don't understand the notion that it is faster to generate repetitive code with keyboard macros. I use Vim-mode exclusively, and while I'm not a Vim master, I don't think there's any set of macros that will do what Copilot can do.

It's not that Copilot is smart. It's that 60% of what I do doesn't require much intelligence to anticipate. It is the 40% that matters, the remainder can be trivially guessed, and this is exactly what Copilot does.

Maybe this will help: you need to imagine with an AI intellisense that with each keystroke, you are collapsing the possibility space down to a smaller, finite number of outcomes. You write exactly what code you need for the dumb AI to predict the rest of it.

There are a LOT of reasons why AI intellisense is not all there yet; it can be distracting; it can try to generate too much at once; none of the tools have LSP integrated, so it will provide bullshit suggestions of library methods that don't exist. This is all true, and yet it is still highly valuable in some domains, for some people.

That said, if you write x86 assembly for a living, you are probably out of luck.

(I write Kotlin, Java for Android apps and services, C++ that is tightly integrated with the SoC. Python and Bash for command-line tools that invoke REST APIs. Copilot is useful for these domains.)
