Everything is more complex Chris
Interesting perspective, but why pick storage as the complexity poster child? I remember when I could adjust the valves and points on my '63 VW bug, Then along came electronic ignition, fuel injection, and onboard computers. I didn't ask for any of those things and I surely can't work on my car anymore but I must admit despite this complexity cars seem to run a lot better and last a whole lot longer than they used to.
Yes storage was easy back when you had some bus & tag cables connected to a few disks on an IBM 360, but as I recall you were maxed out at 32 drives, or about 10GB. Then along came MS Office, Oracle, and oh yeah the interent and suddenly everything got more complicated.
Not sure I'd call it a horror show but its true storage complexity is part of keeping up with the pace of data growth and diversity, whether its in your data center or somebody else's in the cloud. So just as you need a good mechanic with sophisticated diagnostics to work on your car, you'll need a good IT storage architect to sort through all the options and design a proper data storage network.
