ditto!

Soldering chips straight onto the motherboard is much more economical.
You can also reduce the electriciy bill, expenses with air conditioning and costs due to technological evolution using inexpensive low power processors.

Imagine if you could buy a motherboard and just upgrade processor/memory when you find convenient, nothing else, for the next 10 years.
But... if chips will be soldered... how you can replace them?

Answer, in a nutshell: carrier boards and module boards. See this: http://www.qseven-standard.org/

There are carrier boards in popular form factors, like ATX, uATX and mini-ITX.
There are modules boards with processor, memory, LAN controler, PCIe controller ... all in a single small board.
Just plug the module onto the carrier board. You can run Linux, Android and even Windoze on it.

You can build your next set-top box with an inexpensive quad core ARM processor, for example, for under USD$100.
You can build your next powerful workstation, using modules powered by an AMD APU, for example, or an Intel i7.
You can also build a super computer, with hundreds of low power CPU+GPU boards, from a fraction of the price it was a couple of years ago.

Humble end users and rich big corporation are alike: they all appreciate the idea of saving money.
Soon part of these innovations will be available to end users too.

I find difficult to understand what "intelligence" really is. Looks like most tests are actually measuring your ability to recall past experiences or recall semantic information. If you travel a lot, you will possibly perform better on the former family of tests, whilst if you read a lot, you will possibly perform better on the latter family of tests. Despite such abilities are considered part of "intelligence", I'm leaded to think that raising on IQ tests are related more to our exposure to education and visual media than anything else. Other tests are designed to measure other forms of "intelligence", like abstract thinking, but I find difficult to imagine any test which would be absolutely uncorrelated to better abilities to recall past experiences and to retrieve semantic information.

My feeling is that we are as intelligent as we always used to be, but now we have more information stored in our memory. So, when you face a difficult abstract thinking test, well... you've faced that sort of thing before in the college and, by the way, such sort of challenge in the test is not absolutely unknown, you are used to that wording... so, most of circumstances, you will be composing past experiences, semantic reasoning with some flexibility and creativity. Since you are better than your parents on the first two aspects, you will be performing better than your parents.

Also, the example of "dogs and rabitts" (what do they have in common?) makes me believe that eventually abstract reasoning (dogs and rabbits are both mammals) is better rewarded by IQ tests than ability to see things in concrete, utilitarian terms (dogs hunt rabbits). This way the shift from concrete reasoning to abstract reasoning (which is fact) would lead to more intelligence (which is controversial).
