I believe that humans aren't ready for hybrid cars yet. Most of Americans look towards handling and comfort when buying a car, and gas efficiency means close to nothing. If you want towing power, speed that usually doesn't mean hybrid. Though Toyota and Ford are producing hybrid SUVs this year.
The iTunes Music Store beat out the Toyota Prius as the invention of the year (TIMES Magazine). A simplistic online music store, beat out a vehicle that can change the future of transportation as well as environment. Shows how much people care about the latter.
Businesses aren't ready for it either. If more people started buying hybrids, more and more gas stations disappear. That is why the Government is buying time for businesses to prepare.
I know the environment is in need of it though, and I'm ready for it.
Another technology most users aren't ready for are 64-bit PCs. Aside from the G5, there aren't any existing OS for the common user that is made for 64-bit computing, unless you count Linux as one.
In about 2 years, Windows will have a 64-bit version come out.
I think Cloning Technology :(
I don't know about you, but I'm way ready for that, and so is the medical system.
The idea of cloning new organs for the ill (in theory). We need that ready as soon as possible.
Aside from religious people, I think humans want to see this happen.
