in the consumer space, spinning rust will get rarer and rarer as SSDs around the 2-4TB mark prices fall. after all that's pretty much what 99% of people need, and even then that need drops as more and more of regular peoples stuff is in the cloud and media is streamed instead of downloaded/owned/kept. the tiny niche market that's OCAU, who want big storage at home, will be fighting with AWS/GCP/Azure/BackBlaze etc. for HDDs production capacity. and they don't have to worry about budget because someone else is paying for that storage.
