If anything this example shows that these cli tools give regular devs much higher leverage.
There's a lot of software labor that is like, go to the lowest cost country, hire some mediocre people there and then hire some US guy to manage them.
That's the biggest target of this stuff, because now that US guy can just get equal or hight code in both quality and output without the coordination cost.
But unless we get to the point where you can do what I call "hypercode" I don't think we'll see SWEs as a whole category die.
Just like we don't understand assembly but still need technical skills when things go wrong, there's always value in low level technical skills.
