So, having worked in this space decades ago...
The issue with personalized feeds is that it takes a lot of compute power to figure out what each person wants to see. So much, in fact, that it becomes cost-prohibitive.
AI doesn't solve this problem. It never can.
The only way Amazon got around this problem is they didn't personalize feeds. They personalized *products*. So they would grab the last X products you viewed or bought, pull up a list of which products are connected to those, and showed you those products. They never did the full MxN comparison of all the products you bought or viewed and how you connect with other users and what they bought. They just noted that "People who buy X also buy Y", put that in a table, and looked up you last 10 products or whatever.
Maybe what Elon is talking about is allowing someone to provide parameters to their recommendation engine (that's all this kind of AI would be) and then allow multiple people to view that feed. That *may* work, provided the number of people allowed to do this is relatively low, or they pay they cost of computing recommendations somehow.
But you are never going to get personalized recommendations for individuals because it will never be cost-effective to do so.
