A lot of stories like this. Like for example display tech and how LCD screens were received initially.

But there also are examples of failures, things which never became what they were predicted to.

Like blueray, which became a niche product at best, instead of replacing CD/DVD.

Or attempts at large removable magnetic disks, like ZIP drives.

It is impossible to predict how things will go, may be some new storage tech which is not vaporware finally happens and makes flash obsolete before it can replace HDDs…
