To the first part, I agree. A skilled developer who can quickly separate the wheat from the chaff can get a boost out of AI. I'd put it at around 5-10%, but I've had some tiny projects where it was 400% boost. I think it's a small net gain.

As for your second point I just have to disagree. There are no numbers but it is clearly selling the idea of the majority of code being AI generated, and that's bullshit whether it's an outright lie with numbers, or merely vaguely misleading. It's like when someone cuts off the bottom of a graph to make relative change look huge. It wants people to glance at it, get the wrong idea, and move off without curiosity.
