I note that the data in most organizations is proprietary, and not distributed amongst witnesses. While disks are not the maximally fastest data storage solutions, they are considerably less expensive. The point to this is that enabling a variety of innovators to participate in Steem is desirable, while corporations have a different use for their data.

I recall that some of the first automobiles ever on American roads were electric cars. Just because something didn't take over the market, or has been done before, doesn't make it obsolete. Steem is competing with certain aspects of financial, media, and other industries, just as electric cars did with Goodyear and Standard Oil.

I reckon it's more important for myriad nodes to be operated than that each node is using top shelf hardware.

Thanks!
