The uniform growth of single-crystal graphene over wafer-scale areas remains a challenge in the commercial-level manufacturability of various electronic, photonic, mechanical, and other devices based on graphene. Here, we describe wafer-scale growth of wrinkle-free single-crystal monolayer graphene on silicon wafer using a hydrogen-terminated germanium buffer layer. The anisotropic twofold symmetry of the germanium (110) surface allowed unidirectional alignment of multiple seeds, which were merged to uniform single-crystal graphene with predefined orientation. Furthermore, the weak interaction between graphene and underlying hydrogen-terminated germanium surface enabled the facile etch-free dry transfer of graphene and the recycling of the germanium substrate for continual graphene growth.

Ok lets derail the thread to see your point.
the thread was void of any reply until I posted so I cannot subscribe to that theory.

Wait a second
Scotch - tape ?
That's how it got invented in the first place after a student penciled a square on a bit of paper and pulled a thin layer off using sticky tape.
The discovery, Tour said, could be a boon in the cleanup of contaminated sites like the Fukushima nuclear plants damaged by the 2011 earthquake and tsunami. It could also cut the cost of hydraulic fracturing (“fracking”) for oil and gas recovery and help reboot American mining of rare earth metals, he said.
Graphene oxide’s large surface area defines its capacity to adsorb toxins, Kalmykov said. “So the high retention properties are not surprising to us,” he said. “What is astonishing is the very fast kinetics of sorption, which is key.”
“In the probabilistic world of chemical reactions where scarce stuff (low concentrations) infrequently bumps into something with which it can react, there is a greater likelihood that the ‘magic’ will happen with graphene oxide than with a big old hunk of bentonite,” said Steven Winston, a former vice president of Lockheed Martin and Parsons Engineering and an expert in nuclear power and remediation who is working with the researchers. “In short, fast is good.”

No my friend it's not fear it's being educated to see where this will lead.
As i said we need laws to protect us from the use and not allow ourselves to be washed along by the banks and corporations that build these new devices.
Technology today brings us the light bulb that does not burn as long as they did back in the 1920's so I am sorry if I don't share the same blind faith as you do towards these advancements and this comes to you from someone that has a good understanding of physics, science and computers so the argument about running around riding a house holds no water.

The day is fast coming when if you want to safeguard your privacy in any form you will be considered suspect. Because the question you will be asked by others that have submitted to the wiles of technology will be, "So, what do you have to hide?"
