.... Why keep that only in house and why not make competitive public companies?
I don't use Meta products regularly, but they've crowbarred the "Meta AI" feature into everything - FB Messenger, Whatsapp, Instagram... There's even a standalone website to chat with the Meta AI model similar to chatgpt:
I'm certainly prepared to agree that they don't have a huge amount of traction or marketshare, but they absolutely have already built AI products and they exist.
Outside of their own consumer products, there's the family of llama models too etc.
Then they generate unique copy and images for each user (or hyper-targeted bucket of users), tailored to what would make them click. All continuously A/B tested.
They probably want to better target ads and generate outrage slop with AI. That was always the plan: spy on people, make them unhappy, sell ads and maybe also provide the means to scoundrels to scam the elderly in the process.
