What is your experience with Github Copilot?

I installed Github Copilot (VS Code extension) and signed up for the technical preview three days ago. Yesterday I got the invitation, and the extension started working.

I tried it with Erlang and it understands Erlang.

I refactored this code,

-record(person, {
    name,
    age,
    status
}).

to this,

-record(person, {
    name :: string,
    age :: int,
    status :: atom
})

with the help of this extension, and it’s awesome, right?

I think it’s great for learning, what do you think?
