Wrong, they last not much longer than most HDDs, though HDDs require use 1x per year to keep data on them. HDDs arguably have more life than them because they're protected by a much better case often.
SSDs have write/read limitations which makes them less reliable for long term data storage though.
We need to go back to tapes and make them fast. They were getting ok until recently too. You can also store a fuck tonne of shit on them, like nearly 100s of terabytes. It's just a bit slower than HDDs and SSDs. Can also be kinda dicky to use correctly.
Much more longevity though.
