> What’s gone is the tearing, exhausting manual labour of typing every single line of code.

Do I live in a different engineering world? Because that's so much not the exhausting labour part of my work, it's not even the same universe. The exhausting manual labour for me is interacting with others in the project, aligning goals and distributing work, reviewing, testing, even coming up with test concepts, and… actually thinking through what the code conceptually will work like. The most exhausting thing I've done recently is thinking through lock-free/atomic data structures. Ouch, does that shit rack your brain.
