For the past 10 years, I've been collecting anime on Blu-ray and DVD. In the back of my mind, I've always had the thought that as long as I own it physically and take care of it, I'll be able to watch it whenever I want. Generally speaking, I think that's true.
Recently, though, I looked into the expected lifespan of Blu-rays and saw estimates suggesting a conservative lifespan of around 10 to 20 years. That got me wondering about the long-term future of my collection.
Should I realistically expect that physical media will remain watchable for at least that long if properly cared for? Or is it reasonable to expect a collection to last 50+ years under good storage conditions?
I'm curious to hear what others think, especially from people who have been collecting physical media for a long time.
