Right now you can get 20TB hard drives for cheap and setup your own NAS, but way more people spend money every month on Dropbox/iCloud/onedrive - people value convenience and accessibility over “owning” the product.
Companies also lean into this. Just consider Photoshop. It used to be a one-time purchase, then it became a cloud subscription, now virtually every new AI feature uses paid credits. Despite having that fast SoC, Photoshop will still throw your request to their cloud and charge you for it.
The big point still remains: by the time you can run that trillion parameter model at home, it’s old news. If the personal computer of the 80s was good enough, why’s nobody still using one? AI on edge devices will exist, but will forever remain behind data center AI.
