the strange thing about copilot is that it is about writing code but github isn't a code-writing product (besides that text editor they made), it's a version-control & repository product.
through my deeply-rabbit-holed-product-design-theoretical-perspective lens this translates as another manifestation of trying to make something that is concrete in purpose, which gives concrete accountability to the company behind it, into something general in purpose, which dilutes the concrete acocuntability over time.
"This is a public/private version-controlled repository product"
vs
"This is a collaboration and productivity product"
