I would say maybe not depending on what you want to do. Surely Silicon Valley is in CA, but what do you want to do? There are medical device manufacturers all over the world who are developing cutting edge technologies; some really cool stuff is coming out of the US, EU and Middle East.
When you talk about working in technology, you are talking about writing a book. There are billions of books, and different types. You need to narrow that down a bit.
Look up how to do a force field analysis. Use that to help you visually see your interests. Oh, and save that tool to your "tool box". It will likely come in handy later as it is great to help see what force has the most effect on a given phenomena.

Hi. It is true California has a lot of technology jobs due to Silcon Valley, but there are lots of other areas that have technology corriders. Boston has a technology area around MIT as well.
Don't limit yourself geographically, you have plenty of time to make decisions.
