I'm being picky here, but the word "proven" doesn't really make sense in the context. A more accurate way of expressing the title would be "Evidence supports a different theory" or "Less support for this theory", as theories can never be proven.
Is this a serious argument? One could say the same thing about:
1) The advent of modern gardening and genetically modified crops. With increased efficiency, where will the extra farmers go?
2) The advent of computers. What will happen to books? The tree cutters? The people who ship the trees to the lumber plant?
I could go on and on about ANY technological advance in the last 200 years. I don't see how cars are any different that will bring "marxism or communism".
Certainly all true points. However, for the people without the luxury of 16GB (I'm running on an old machine, with 3gb of RAM), Chrome consistently freezes the computer due to the resource hogging. I've learned my lesson and switched to Firefox.
