Windows hate train looks fun, but as someone who works in the industry, most of that code is probably just unit tests and boilerplate stuff.
Copilot is decent at quickly writing huge amounts of tedious unit test code, requiring minimal tweaks. And since Microsoft works with languages like C# and .NET for their native apps, and likely backend too, there is quite a bit of verbosity that Copilot can take care of.
No real code is AI-generated. He’s just saying shit like this to keep idiot investors happy.
