Sure, but one result of that is that in SV, networking is less important. You can email your resume to a recruiter at any funded company, they'll fly you out for an interview, nobody is expected to know anything about you other than what they can discern in an interview. You'll get 5 to 10 thousand dollars in relocation/sign-on bonus. And the salaries are significantly higher than in Tennessee.
Salaries are higher in SV, but you'll have more disposable income in Nashville, and probably a more comfortable home. Also, the local politics and culture are different. As much as it may surprise the people who do like it, some people don't like the way California operates.
I looked into moving there, for the opportunity. I networked. I had (I flatter myself perhaps) the right skill set for my niche.
I looked at the cost of living.
I've got kids, two dogs. For any kind of a reasonable non-sh*tty living situation I'd double my living expenses, plus a two-hour commute.
I moved to Nashville instead.
