I agree. I hate the idea of Meta or anybody having that much data on me in one place. However - - even Amazon, which supposedly has some of the most sophisticated purchase data and analytics out there doesn't seem to be able to do anything with it. I mean, I buy a blender there and the next thing they recommend to me is... A blender. That only stops until I buy something else which they then continue to recommend more of, as if I only want multiples of the exact things I've already purchased. The recommendation engine is the whole point of having my data to begin with so but they seem unable to recommend anything new to me at all.

It's like they have all this information written in front of them but they can't read.
