I remember there was an ad "myth" about the fact that adtech companies become so good at targeting they would start advertising nappies to a household and parents would be surprised as to why when their daughter had been pregnant and didn't know about that (or along those lines). None of that were ever true (well, unless you accept the simplest explanation for that anecdote that the daughter accidentally Googled something related), this is definitely not true as of today.
