> Say hypothetically the productivity boost from AI is 2x per employee

I believe this is a bad assumption. Most likely the boost is not normally distributed. So, although all employees become more productive, some employees become much more productive thereby making the others redundant.

As someone pointed out already... there are diminishing returns. In addition, there are marginal returns. Put the two together and you get ever diminishing marginal returns from the laggard employees.
