This is a chicken-little story.

We've been putting many computer eggs in one hardware basket for a long, long time.
What do you think mainframes running MVS and VM/CMS were?
What were things like air traffic control?

The 'desktop' is a fuzz concept that gets confused with a GUI.
Those mainframes - think airline ticket and reservation - could handle many hundreds of remote terminals, keeping them updated.

What's a dumb terminal if not the ultimate in 'thin clients'?
