Sorry, my mistake. Replace "today" with "someday".

For "today", I've seen good engineers solving specific tasks in a third of the time already, but I won't make specific claims about absolute productivity multipliers.

Specific is the important word here. Some boring tasks that can be automated in all jobs will be automated though you still need to check the AI. I assume no competent developer was fired because of that productivity boost in that specific task

You don't need to "fire" anyone for AI to cause a significant impact. All AI needs to do is to allow companies postpone hiring more people.

I really don't understand why you are being so obtuse about this. Do you honestly think that you can make the argument that software development (as an industry) is somehow immune to automation?
