No way I am going to trust today's guessificial algorithm. The capacity/cost does scale as the file size increases, and the algorithms get smarter. Photos can increasingly be analyzed for useful correlation. Today we can find by time, place, people, object, eventually scenes will be reconstructed, lifestyle patterns contributing to long term health outcomes, leading to real diagnosis, memory augmentation and simulation (much of it requiring better privacy). In the meantime, I enjoy being able to time travel to amazing or obscure moments (even if it's just that amazing abricotine in 2016).
