Name one product that Meta created over the last 10 years that mattered - beyond adtech. They can fire everyone in every team and just retain ads (tech and sales) - and some minimal setup for instagram and whatsapp and facebook and their revenue will not take a dent. So, yes, they overhired.
Oculus? Not created, but if you buy a VR headset, Meta Oculus is one of the top choices.
This comment put everything into perspective. I can't name anything beyond Facebook, Instagram or Whatsapp that Meta's created and I've used in the past 10 years.
I've never even (knowingly) used the LLama models tbh.
