The A/B test infrastructure is. It’s easy to wire up experiments because there is always a template/recipe to do so. Multiple subsystems can be strung together (eg: Experiment arm XX in subsystem A triggers Experiment arm YY in subsystem B). Analysis is simplified too since all the core metrics are already in place and ready for analysis.

What does "ridiculously simplified" mean here? Is it that the test infrastructure in Big Tech is very mature and easy to use?
