That's easy: a management team that only needs ~X new features per month, not 4X. No organization has an infinite demand for features. If they currently have 50 devs working on the platform, maybe after quadrupling the productivity of each dev they'll keep 20. Speed of development increases by 60% and they save 30 developers worth of expenses, which means hefty end-of-year bonuses for every manager up the chain. More likely they keep about 13-15. It's naive and boneheaded to insist that productivity increases never result in layoffs.
