The financial crisis will not affect us?

It would seem that stockbrokers go crazy, banks burst, but what do we need? Computers and Internet technologies have become so firmly established in our life that this industry should only grow and flourish.
But no. Yesterday came the news of the restructuring of the assets of AMD, actually getting rid of its plants. And if you look closely at the value of shares of leading companies in the IT sector, this does not seem like a special case.
These indicators are obtained if we compare the stock price a year ago and today:

1. Nvidia: -81%
2. Sun Microsystems: -76%
3. AMD: -68%
4. Ebay: -59%
5. Yahoo: -57%
6. Apple: -56%
7. Dell: -56%
8. Google: -54%
9. Cisco: -45%
10. Intel: -42%
11. Adobe: -40%
12. Microsoft: -31%
13. Oracle: -28%
14. IBM: -26%
15. HP: -25%

In total, the 15 companies mentioned above have lost in their value about 570 billion dollars in just one year! Of these, more than a hundred billion accounted for only by Google, which set an absolute record fall in dollar terms.
Of course, this does not mean that the world will be swallowed up in darkness and chaos, but the optimism in the IT sphere will surely be diminished. While everyone was waiting for the crisis in Web 2.0, companies from a more traditional sector were under attack.
