How do I touch this?

Knowledge - how to touch this? Investors can say when they are holding their credit cards or even the money itself.
Last week google papers value in NASDAQ broke the $500 dollars boundary (not bad for a company whose has opened its papers for $85). But, did you ever touch in anything created by Google?
Submarino (Brazil) and Americanas.com jointed into a new company - a 8 billion company. But you cannot touch in anything from them, expect the sold products (whose are not produced by them). There's no factories, not a huge infrastructure - but a huge investment on T.I and accessibility.
It doesn't means that there will not be anymore factories in the world. It just means that the way the business is coming has changed. We need more than ever clothes, food, security and other services - but the way we get it, it's changing and will change much more.
