That's going to happen in all of big tech (already happening at Amazon and Microsoft). These companies have too many employees. It was never really justified and with AI even more so. I've been in big tech and directors often tell everyone to hire when they can rather when they need. For example, if they know a hiring freeze is coming, they will try to hire as many people as they can before it happens. It's rare to find people in big tech where their incentives align with the company. (and the blame is not always on the people themselves)

As for Meta, I give Mark credit for trying, even if he failed so far with all the VR stuff. The main disappointment is about Llama cause it's clearly an execution problem. With Meta's investments in AI throughout the years, not being able to compete with Anthropic and OpenAI is a big failure.
