Simple answer is tech has gone backwards on average in my opinion. The pieces are there for better gadgets but something always cripples the gadget that ends up on the store shelf.
disclosure: my predictions are not that old, can only go back to the 70s and all the predictions actually come from the 90s
With the 386, internet (not just the web at that point) , memory, OS's, electronics (PDA's, displays, etc) I thought we had the base features there and now the cool things could be built:
CPU in everything once cost came down from mass production and refinement, small always available computers with network, electronic files instead of paper, communication in multiple forms all the time.
We have crippled forms of all of this, but every time we get close to it being common, standard and "faded into the background" something happens that stops progress and it has to be restarted.
I was hoping desktop computers would "fade into the desk" , laptops and such are ALMOST there but not quite. Social networking using tech is ALMOST faded into common usage but not quite as FB and other silos fight over users and screw up personal data.
So my answer is "No, things missed what I predicted" mainly as a frustration that they ALMOST get there time and again then fall down.
