Sorta changing topics, 3D Printing is the ultimate attack on Everything. (Except for industrial grade processes. Those will last a little longer.) Being able to buy a "75 pound lump of 50 compounds" at YourCostBulkClub (CostCo, BJ's are East Coast USA examples), 3d Printing lets you make (almost) ANYTHING with just a software routine, and you know the Open Source movement will be all over that.
Hence the desperate moves to block the tech at this early stage. Need a kitchen knife? Print one. Need a Cereal Bowl? Print one. Need a plastic tin for laundry? Print one.
But wait. It gets WAY worse. Need a toy for your 4 year old? (Non-Genius.) PRINT ONE. I bet you will be able to print a cheap car-thingy soon. Your 4 year old won't care. He can zoom it around. Toys 'R Us and Hasbro/Mattel/whoever will NOT be pleased that their "cheap plastic crap" business model will be sunk.
And more, but I'll let y'all imagine how disruptive it can be.
