Because a human would at least consider if a termination is warranted. Humans make mistakes but by my experience, software tends to produce wrong results more often than humans. Therefore, for all important decisions it makes sense to always have human making the ultimate decision and consider if there is no prospect of performance improving. And even if the human doesn't do a better job, it's still the nicer way to be told by a person rather than a machine that you lost your job.
