RE: Bitcoin Security Overview & Quantum Computers
I see. Well, I bet early users of massive mainframe systems in the previous century never imagined computers would become a household technology either. Who knows how things will change in 20 or 30 years?
Regarding tablets, you could make a case either way. Maybe it's more accurate to call them a supplementary technology. But I suspect the average non-techie person (like my wife) uses some tablet device (iPad, smartphone) a lot more frequently than the desktop PC gathering dust on their desk. So in that sense, tablets are an evolution in terms of market share and how much they have proliferated into mainstream society & culture.
There will always be a place for the venerable old desktop, however. I personally can't imagine how I would survive without one.
Yes I agree, miniaturized gadgets probably appeal more to women, whereas men like traditional old school stuff. I personally like laptops and PC's, but I dont own a tablet, nor do I want to, I see no use in them.
As for a quantum PC, I highly doubt it, this is not a question of efficiency, but a question of physical limits. A QC requires too much energy just to maintain the quantum state, not to mention the calculation part itself. I think it will only be used for large scale research projects, and by governments, but hardly by mainstream.
I think most of those documentary films are wishful thinking, they like to assume things in the future that just wont be true.
But who knows maybe I'm wrong.
