One family down the street from me still drives a Saturn! Yet no one is going to say "Saturn isn't dead!".

Nope. It is like - suddenly every truck everywhere is Saturn. The unit count may be lower but the total tonnage moved grows. While HDD shipments have fallen fourfold counted in units, if you check total exabytes delivered you will see they are shipping a lot.

HDDs would be much more important today if flash storage didn’t exist.

did you know that SSD are not memory stable if they dont get electricity every now and again...

Spinning platters are prone to catastrophic mechanical failure and tape can undergo delamination. What of it?

Do you know how much data is stored on ssds in data centres?
