AI is not responsible for anything at the moment, except making existing senior developers reasonably more efficient for sleeve of tasks, but not the tasks that take the most time.
Saying "we don't need as many staff because AI" is an oft-repeated trope because it sounds like a reasonable excuse to fire people. It's nearly impossible to back up the claim with any measurable method, and investors will look aside on the mismanagement and/or ridiculously over-engineered/over-complicated custom tech stacks companies run if they say "AI" anywhere in their reports.
