Let's also not forget a lot of the market edge of SWEs comes in knowing how to navigate these parts. The fact you needed to be reasonably fluent in a language was already a barrier to entry which meant in better times new grads could earn six figures at their first job just for putting in that effort.

Maybe you will still be needed. That is one question. How well you will be paid and treated when the barrier to entry is now "I can think" is another. As the parent indicates, most people doing software are not doing things akin to pure math. I don't think most SWEs want that lifestyle anyway.

It's ok. You shouldn't fight the coming change. Instead use the time we still have to fight for more equal outcomes (vote for politicians that support UBI, Medicare for all). The longer you delude yourself that you are uniquely needed in an increasingly mechanized world the worse all our outcomes will be.
