I really missed those days that I could write URLs I visited frequently on notebook. Unfortunately, we might never be no way back to the good old days. There is literally way too much info on the internet, and thus impossible to index contents manually.
I dont think it is as hopeless as you think. There are only so many websites people actually use for human-created content. Those should be prioritized. There is still the issue of differentiating between bot blogs and human blogs but I'm sure I could figure something out at a 200k salary, and google has plenty of people like that
