The funny thing is - we need less. Less of everything. But an up-tick in quality.
This seems to happen with humans with everything - the gates get opened, enabling a flood of producers to come in. But this causes a mountain of slop to form, and overtime the tastes of folks get eroded away.
Engineers don't need to write more lines of code / faster - they need to get better at interfacing with other folks in the business organisation and get better at project selection and making better choices over how to allocate their time. Writing lines of code is a tiny part of what it takes to get great products to market and to grow/sustain market share etc.
But hey, good luck with that - ones thinking power is diminished overtime by interacing with LLMs etc.
