Layoffs via Algorithm

I am sure everyone has heard of the layoffs at Google and how it was handled poorly. Especially with the ten thousand employees notified at night via email, causing many employees to learn they no longer work there by their badge not working since they missed the email.

If that was bad enough, I read all of the 10,000 employees were selected based off an algorithm of performance ranking where there was little input from managers on the performance/value of the individuals on the team.

So there is the Google spin of using an algorithm allows Google to remove prejudice when deciding who to layoff. Which I agree its good not to be prejudice, so they win there.

However, I feel like this isn't the right way to handle this since there are so many instances where a ranking might layoff the wrong people.

I would think of top performers who just came back from maternity/paternity who are still getting back into the swing of things or employees who take on additional responsibility to help train new hires, will then get impacted more since the ranking systems might not account for more "human" qualities in a worker.

Also since Google Execs relied on a ranking system to decide who to layoff, did that cause them to be less human when letting all of the employees go?

IDK, is it just the "boomer" in me not fulling trusting AI. Or am I not alone is my thoughts on this? Or am I just an old man yelling at the sky since this post won't change anything?
