Am I the only one that sees the problem with Quantum Computing being its potential power if it actually turns out to be possible? I mean say the first product is a monstrosity, but fits within the actual quantum computing boundaries and therefore can be called a Quantum Computer. If you give it the rough time line of 40 years similar to computers to work out the kinks and get down to a marketable level, wouldn't it be very hard to push new products?
I can definitely see the capitalism argument since it will ultimately be corporations that bring such technology to the masses, but with so much "easy" potential after the initial concept is designed, built, and tested, it just seems like the end all solution for nobody to upgrade further. Of course software would have to be redesigned to take advantage of its potential, but I don't think the average Joe would probably notice much of a difference between a 300 qubit processor and a 200 qubit processor and most likely wouldn't even need to look much further. Then again I'm a n00b in Quantum Physics so maybe I'm just getting it all wrong.
It does scare the hell out of me thinking what Governments could do if it became a reality. Then again I'll be long dead to not see the possible negative impacts it could have on the populace, given technology is a double edged sword. A very sharp one if that.
