Meta’s experiment to replace their human workforce

Hopefully you didn’t miss the latest news about Meta’s experiment to replace a good chunk of their engineers with AI Agents.
Allegedly (this is all from leaks), they were going to try to take their 10-20 person teams and shrink them down to 3-5 people.
The result (allegedly) was that time spent debugging went up by 70%. Having had to code review and debug code created by a non-programmer vibe coding intern, I am not surprised by this.
Incidents such as service disruptions and data leaks went up by 40%... Wow… just wow.
I would love to know exactly what that cost them so I can compare it to how much they “saved” by laying off those engineers.
Clearly the ROI was not in their favor.
In their own words, AI agents were performing “large-scale, disruptive actions that humans are unlikely to execute”.
While I think there is a lot of practical application of this technology, there is also a lot of hype around it as well.
It’s not going away anytime soon, but let's also be practical about its application.
