i totally know how you feel since i have felt that way in the past as well :) here's something relevant: http://pgbovine.net/practical-reason-to-pursue-PhD.htm

my two cents: find something where the grants align with your interests, or find a brand-new faculty member who has startup money so isn't as bound by grants in the near term. and if things don't work out, simply leave and go to industry -- with a marketable skill set like what you get from being a CS major, there's no way for you to lose. go wherever has work that you like more.
