The other day, I had a talk with my dad and he asked me about why YouTube is recommending him videos that he saw in the past or that type of ads. He is a non-techie btw.
I told him about personalized ads and so on.
Told him the "advantages" and the disadvantages of it. I even explained the advantages like if they would be so good that they are on the same level as holy things that happened to humanity. That was just to test him though.
And guess what?
He was completely against it. He said that it just brings disadvantages and no advantages at all. He was pissed that YouTube was recording his search history and so on to make a profile of him. He cares for his privacy. And I'm proud to have such a dad. :)
