If LLMs really multiply productivity, why would you fire people and handicap the boost?

I have 100 people that can now do the work of 200 people thanks to a new tool.

How is the logical response to fire half of them and bring my productivity back to where it was before?

I would say the vast majority of people in this thread don't believe that this is related to AI at all, other than as a pretext. It's kind of incredible.
