LOL!
I have 14 years worth of burned CDs, obsolete photo cards, and thumb drives of photos I need to secure before I actually do lose them. Almost lost my honeymoon photos.
70 year old film definitely holds better than these formats.
We went through mom’s old albums the couple of weeks before she died at 94. Her mind was still sharp as a tack as she went through the photos all the way back to when she was three years old. Names of friends and all of the stories. We were very lucky. And most of the old black and white photos were probably as sharp as the day they were taken. The color ones from the seventies weren’t the greatest iirc.
Many people don't realize that the lifespan of CDs is limited. Some brands are better than others. But many cheap brands have a thin layer that will degrade and flake off after a couple decades, rendering the digital data unreadable. Best option is to get a photo processing place to print your most cherished photos to both paper and a new CD/DVD. At least on paper, a photo will last for many decades (professional silver paper, not inkjet printed paper!).
